-Phonet Pipe-controller Implementation
--------------------------------------
-
-Phonet Pipe-controller is enabled by selecting the CONFIG_PHONET_PIPECTRLR Kconfig
-option. It is useful when communicating with those Nokia Modems which do not
-implement Pipe controller in them e.g. Nokia Slim Modem used in ST-Ericsson
-U8500 platform.
-
-The implementation is based on the Data Connection Establishment Sequence
-depicted in 'Nokia Wireless Modem API - Wireless_modem_user_guide.pdf'
-document.
-
-It allows a phonet sequenced socket (host-pep) to initiate a Pipe connection
-between itself and a remote pipe-end point (e.g. modem).
-
-The implementation adds socket options at SOL_PNPIPE level:
-
- PNPIPE_PIPE_HANDLE
-	It accepts an integer argument for setting value of pipe handle.
-
-  PNPIPE_ENABLE accepts one integer value (int). If set to zero, the pipe
-    is disabled. If the value is non-zero, the pipe is enabled. If the pipe
-    is not (yet) connected, ENOTCONN is error is returned.
-
-The implementation also adds socket 'connect'. On calling the 'connect', pipe
-will be created between the source socket and the destination, and the pipe
-state will be set to PIPE_DISABLED.
-
-After a pipe has been created and enabled successfully, the Pipe data can be
-exchanged between the host-pep and remote-pep (modem).
-
-User-space would typically follow below sequence with Pipe controller:-
--socket
--bind
--setsockopt for PNPIPE_PIPE_HANDLE
--connect
--setsockopt for PNPIPE_ENCAP_IP
--setsockopt for PNPIPE_ENABLE
+  PNPIPE_HANDLE is a read-only integer value. It contains the underlying
+    identifier ("pipe handle") of the pipe. This is only defined for
+    socket descriptors that are already connected or being connected.

  *		Microchip Technology, 24C01A/02A/04A Data Sheet
  *			available in PDF format from www.microchip.com
  *
- * Change History
- *
- *	Tigran Aivazian <tigran@sco.com>:	TLan_PciProbe() now uses
- *						new PCI BIOS interface.
- *	Alan Cox	<alan@lxorguk.ukuu.org.uk>:
- *						Fixed the out of memory
- *						handling.
- *
- *	Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
- *
- *	v1.1 Dec 20, 1999    - Removed linux version checking
- *			       Patch from Tigran Aivazian.
- *			     - v1.1 includes Alan's SMP updates.
- *			     - We still have problems on SMP though,
- *			       but I'm looking into that.
- *
- *	v1.2 Jan 02, 2000    - Hopefully fixed the SMP deadlock.
- *			     - Removed dependency of HZ being 100.
- *			     - We now allow higher priority timers to
- *			       overwrite timers like TLAN_TIMER_ACTIVITY
- *			       Patch from John Cagle <john.cagle@compaq.com>.
- *			     - Fixed a few compiler warnings.
- *
- *	v1.3 Feb 04, 2000    - Fixed the remaining HZ issues.
- *			     - Removed call to pci_present().
- *			     - Removed SA_INTERRUPT flag from irq handler.
- *			     - Added __init and __initdata to reduce resisdent
- *			       code size.
- *			     - Driver now uses module_init/module_exit.
- *			     - Rewrote init_module and tlan_probe to
- *			       share a lot more code. We now use tlan_probe
- *			       with builtin and module driver.
- *			     - Driver ported to new net API.
- *			     - tlan.txt has been reworked to reflect current
- *			       driver (almost)
- *			     - Other minor stuff
- *
- *	v1.4 Feb 10, 2000    - Updated with more changes required after Dave's
- *	                       network cleanup in 2.3.43pre7 (Tigran & myself)
- *	                     - Minor stuff.
- *
- *	v1.5 March 22, 2000  - Fixed another timer bug that would hang the driver
- *			       if no cable/link were present.
- *			     - Cosmetic changes.
- *			     - TODO: Port completely to new PCI/DMA API
- *			     	     Auto-Neg fallback.
- *
- * 	v1.6 April 04, 2000  - Fixed driver support for kernel-parameters. Haven't
- * 			       tested it though, as the kernel support is currently
- * 			       broken (2.3.99p4p3).
- * 			     - Updated tlan.txt accordingly.
- * 			     - Adjusted minimum/maximum frame length.
- * 			     - There is now a TLAN website up at
- * 			       http://hp.sourceforge.net/ 
- *
- * 	v1.7 April 07, 2000  - Started to implement custom ioctls. Driver now
- * 			       reports PHY information when used with Donald
- * 			       Beckers userspace MII diagnostics utility.
- *
- * 	v1.8 April 23, 2000  - Fixed support for forced speed/duplex settings.
- * 			     - Added link information to Auto-Neg and forced
- * 			       modes. When NIC operates with auto-neg the driver
- * 			       will report Link speed & duplex modes as well as
- * 			       link partner abilities. When forced link is used,
- * 			       the driver will report status of the established
- * 			       link.
- * 			       Please read tlan.txt for additional information.
- * 			     - Removed call to check_region(), and used
- * 			       return value of request_region() instead.
- *
- *	v1.8a May 28, 2000   - Minor updates.
- *
- *	v1.9 July 25, 2000   - Fixed a few remaining Full-Duplex issues.
- *	                     - Updated with timer fixes from Andrew Morton.
- *	                     - Fixed module race in TLan_Open.
- *	                     - Added routine to monitor PHY status.
- *	                     - Added activity led support for Proliant devices.
- *
- *	v1.10 Aug 30, 2000   - Added support for EISA based tlan controllers
- *			       like the Compaq NetFlex3/E.
- *			     - Rewrote tlan_probe to better handle multiple
- *			       bus probes. Probing and device setup is now
- *			       done through TLan_Probe and TLan_init_one. Actual
- *			       hardware probe is done with kernel API and
- *			       TLan_EisaProbe.
- *			     - Adjusted debug information for probing.
- *			     - Fixed bug that would cause general debug information
- *			       to be printed after driver removal.
- *			     - Added transmit timeout handling.
- *			     - Fixed OOM return values in tlan_probe.
- *			     - Fixed possible mem leak in tlan_exit
- *			       (now tlan_remove_one).
- *			     - Fixed timer bug in TLan_phyMonitor.
- *			     - This driver version is alpha quality, please
- *			       send me any bug issues you may encounter.
- *
- *	v1.11 Aug 31, 2000   - Do not try to register irq 0 if no irq line was
- *			       set for EISA cards.
- *			     - Added support for NetFlex3/E with nibble-rate
- *			       10Base-T PHY. This is untestet as I haven't got
- *			       one of these cards.
- *			     - Fixed timer being added twice.
- *			     - Disabled PhyMonitoring by default as this is
- *			       work in progress. Define MONITOR to enable it.
- *			     - Now we don't display link info with PHYs that
- *			       doesn't support it (level1).
- *			     - Incresed tx_timeout beacuse of auto-neg.
- *			     - Adjusted timers for forced speeds.
- *
- *	v1.12 Oct 12, 2000   - Minor fixes (memleak, init, etc.)
- *
- * 	v1.13 Nov 28, 2000   - Stop flooding console with auto-neg issues
- * 			       when link can't be established.
- *			     - Added the bbuf option as a kernel parameter.
- *			     - Fixed ioaddr probe bug.
- *			     - Fixed stupid deadlock with MII interrupts.
- *			     - Added support for speed/duplex selection with
- *			       multiple nics.
- *			     - Added partly fix for TX Channel lockup with
- *			       TLAN v1.0 silicon. This needs to be investigated
- *			       further.
- *
- * 	v1.14 Dec 16, 2000   - Added support for servicing multiple frames per.
- * 			       interrupt. Thanks goes to
- * 			       Adam Keys <adam@ti.com>
- * 			       Denis Beaudoin <dbeaudoin@ti.com>
- * 			       for providing the patch.
- * 			     - Fixed auto-neg output when using multiple
- * 			       adapters.
- * 			     - Converted to use new taskq interface.
- *
- * 	v1.14a Jan 6, 2001   - Minor adjustments (spinlocks, etc.)
- *
- *	Samuel Chessman <chessman@tux.org> New Maintainer!
- *
- *	v1.15 Apr 4, 2002    - Correct operation when aui=1 to be
- *	                       10T half duplex no loopback
- *	                       Thanks to Gunnar Eikman
- *
- *	Sakari Ailus <sakari.ailus@iki.fi>:
- *
- *	v1.15a Dec 15 2008   - Remove bbuf support, it doesn't work anyway.
- *

+	---help---
+	  This option will enable debug tracing output for the iwlwifilegacy
+	  drivers.
+
+	  This will result in the kernel module being ~100k larger.  You can
+	  control which debug output is sent to the kernel log by setting the
+	  value in
+
+		/sys/class/net/wlan0/device/debug_level
+
+	  This entry will only exist if this option is enabled.
+
+	  To set a value, simply echo an 8-byte hex value to the same file:
+
+		  % echo 0x43fff > /sys/class/net/wlan0/device/debug_level
+
+	  You can find the list of debug mask values in:
+		  drivers/net/wireless/iwlwifilegacy/iwl-debug.h
+
+	  If this is your first time using this driver, you should say Y here

+	depends on IWLWIFI_LEGACY
+	depends on EVENT_TRACING
+	help
+	  Say Y here to trace all commands, including TX frames and IO
+	  accesses, sent to the device. If you say yes, iwlwifilegacy will
+	  register with the ftrace framework for event tracing and dump
+	  all this information to the ringbuffer, you may need to
+	  increase the ringbuffer size. See the ftrace documentation
+	  for more information.
+
+	  When tracing is not enabled, this option still has some
+	  (though rather small) overhead.

+ *
+ *
+ * FILLING THE RATE TABLE
+ *
+ * Given a particular initial rate and mode, as determined by the rate
+ * scaling algorithm described below, the Linux driver uses the following
+ * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
+ * Link Quality command:
+ *
+ *
+ * 1)  If using High-throughput (HT) (SISO or MIMO) initial rate:
+ *     a) Use this same initial rate for first 3 entries.
+ *     b) Find next lower available rate using same mode (SISO or MIMO),
+ *        use for next 3 entries.  If no lower rate available, switch to
+ *        legacy mode (no HT40 channel, no MIMO, no short guard interval).
+ *     c) If using MIMO, set command's mimo_delimiter to number of entries
+ *        using MIMO (3 or 6).
+ *     d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
+ *        no MIMO, no short guard interval), at the next lower bit rate
+ *        (e.g. if second HT bit rate was 54, try 48 legacy), and follow
+ *        legacy procedure for remaining table entries.
+ *
+ * 2)  If using legacy initial rate:
+ *     a) Use the initial rate for only one entry.
+ *     b) For each following entry, reduce the rate to next lower available
+ *        rate, until reaching the lowest available rate.
+ *     c) When reducing rate, also switch antenna selection.
+ *     d) Once lowest available rate is reached, repeat this rate until
+ *        rate table is filled (16 entries), switching antenna each entry.
+ *
+ *
+ * ACCUMULATING HISTORY
+ *
+ * The rate scaling algorithm for 4965 devices, as implemented in Linux driver,
+ * uses two sets of frame Tx success history:  One for the current/active
+ * modulation mode, and one for a speculative/search mode that is being
+ * attempted. If the speculative mode turns out to be more effective (i.e.
+ * actual transfer rate is better), then the driver continues to use the
+ * speculative mode as the new current active mode.
+ *
+ * Each history set contains, separately for each possible rate, data for a
+ * sliding window of the 62 most recent tx attempts at that rate.  The data
+ * includes a shifting bitmap of success(1)/failure(0), and sums of successful
+ * and attempted frames, from which the driver can additionally calculate a
+ * success ratio (success / attempted) and number of failures
+ * (attempted - success), and control the size of the window (attempted).
+ * The driver uses the bit map to remove successes from the success sum, as
+ * the oldest tx attempts fall out of the window.
+ *
+ * When the 4965 device makes multiple tx attempts for a given frame, each
+ * attempt might be at a different rate, and have different modulation
+ * characteristics (e.g. antenna, fat channel, short guard interval), as set
+ * up in the rate scaling table in the Link Quality command.  The driver must
+ * determine which rate table entry was used for each tx attempt, to determine
+ * which rate-specific history to update, and record only those attempts that
+ * match the modulation characteristics of the history set.
+ *
+ * When using block-ack (aggregation), all frames are transmitted at the same
+ * rate, since there is no per-attempt acknowledgment from the destination
+ * station.  The Tx response struct iwl_tx_resp indicates the Tx rate in
+ * rate_n_flags field.  After receiving a block-ack, the driver can update
+ * history for the entire block all at once.
+ *
+ *
+ * FINDING BEST STARTING RATE:
+ *
+ * When working with a selected initial modulation mode (see below), the
+ * driver attempts to find a best initial rate.  The initial rate is the
+ * first entry in the Link Quality command's rate table.
+ *
+ * 1)  Calculate actual throughput (success ratio * expected throughput, see
+ *     table below) for current initial rate.  Do this only if enough frames
+ *     have been attempted to make the value meaningful:  at least 6 failed
+ *     tx attempts, or at least 8 successes.  If not enough, don't try rate
+ *     scaling yet.
+ *
+ * 2)  Find available rates adjacent to current initial rate.  Available means:
+ *     a)  supported by hardware &&
+ *     b)  supported by association &&
+ *     c)  within any constraints selected by user
+ *
+ * 3)  Gather measured throughputs for adjacent rates.  These might not have
+ *     enough history to calculate a throughput.  That's okay, we might try
+ *     using one of them anyway!
+ *
+ * 4)  Try decreasing rate if, for current rate:
+ *     a)  success ratio is < 15% ||
+ *     b)  lower adjacent rate has better measured throughput ||
+ *     c)  higher adjacent rate has worse throughput, and lower is unmeasured
+ *
+ *     As a sanity check, if decrease was determined above, leave rate
+ *     unchanged if:
+ *     a)  lower rate unavailable
+ *     b)  success ratio at current rate > 85% (very good)
+ *     c)  current measured throughput is better than expected throughput
+ *         of lower rate (under perfect 100% tx conditions, see table below)
+ *
+ * 5)  Try increasing rate if, for current rate:
+ *     a)  success ratio is < 15% ||
+ *     b)  both adjacent rates' throughputs are unmeasured (try it!) ||
+ *     b)  higher adjacent rate has better measured throughput ||
+ *     c)  lower adjacent rate has worse throughput, and higher is unmeasured
+ *
+ *     As a sanity check, if increase was determined above, leave rate
+ *     unchanged if:
+ *     a)  success ratio at current rate < 70%.  This is not particularly
+ *         good performance; higher rate is sure to have poorer success.
+ *
+ * 6)  Re-evaluate the rate after each tx frame.  If working with block-
+ *     acknowledge, history and statistics may be calculated for the entire
+ *     block (including prior history that fits within the history windows),
+ *     before re-evaluation.
+ *
+ * FINDING BEST STARTING MODULATION MODE:
+ *
+ * After working with a modulation mode for a "while" (and doing rate scaling),
+ * the driver searches for a new initial mode in an attempt to improve
+ * throughput.  The "while" is measured by numbers of attempted frames:
+ *
+ * For legacy mode, search for new mode after:
+ *   480 successful frames, or 160 failed frames
+ * For high-throughput modes (SISO or MIMO), search for new mode after:
+ *   4500 successful frames, or 400 failed frames
+ *
+ * Mode switch possibilities are (3 for each mode):
+ *
+ * For legacy:
+ *   Change antenna, try SISO (if HT association), try MIMO (if HT association)
+ * For SISO:
+ *   Change antenna, try MIMO, try shortened guard interval (SGI)
+ * For MIMO:
+ *   Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
+ *
+ * When trying a new mode, use the same bit rate as the old/current mode when
+ * trying antenna switches and shortened guard interval.  When switching to
+ * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
+ * for which the expected throughput (under perfect conditions) is about the
+ * same or slightly better than the actual measured throughput delivered by
+ * the old/current mode.
+ *
+ * Actual throughput can be estimated by multiplying the expected throughput
+ * by the success ratio (successful / attempted tx frames).  Frame size is
+ * not considered in this calculation; it assumes that frame size will average
+ * out to be fairly consistent over several samples.  The following are
+ * metric values for expected throughput assuming 100% success ratio.
+ * Only G band has support for CCK rates:

+ * REPLY_SCAN_CMD = 0x80 (command)
+ *
+ * The hardware scan command is very powerful; the driver can set it up to
+ * maintain (relatively) normal network traffic while doing a scan in the
+ * background.  The max_out_time and suspend_time control the ratio of how
+ * long the device stays on an associated network channel ("service channel")
+ * vs. how long it's away from the service channel, i.e. tuned to other channels
+ * for scanning.
+ *
+ * max_out_time is the max time off-channel (in usec), and suspend_time
+ * is how long (in "extended beacon" format) that the scan is "suspended"
+ * after returning to the service channel.  That is, suspend_time is the
+ * time that we stay on the service channel, doing normal work, between
+ * scan segments.  The driver may set these parameters differently to support
+ * scanning when associated vs. not associated, and light vs. heavy traffic
+ * loads when associated.
+ *
+ * After receiving this command, the device's scan engine does the following;
+ *
+ * 1)  Sends SCAN_START notification to driver
+ * 2)  Checks to see if it has time to do scan for one channel
+ * 3)  Sends NULL packet, with power-save (PS) bit set to 1,
+ *     to tell AP that we're going off-channel
+ * 4)  Tunes to first channel in scan list, does active or passive scan
+ * 5)  Sends SCAN_RESULT notification to driver
+ * 6)  Checks to see if it has time to do scan on *next* channel in list
+ * 7)  Repeats 4-6 until it no longer has time to scan the next channel
+ *     before max_out_time expires
+ * 8)  Returns to service channel
+ * 9)  Sends NULL packet with PS=0 to tell AP that we're back
+ * 10) Stays on service channel until suspend_time expires
+ * 11) Repeats entire process 2-10 until list is complete
+ * 12) Sends SCAN_COMPLETE notification
+ *
+ * For fast, efficient scans, the scan command also has support for staying on
+ * a channel for just a short time, if doing active scanning and getting no
+ * responses to the transmitted probe request.  This time is controlled by
+ * quiet_time, and the number of received packets below which a channel is
+ * considered "quiet" is controlled by quiet_plcp_threshold.
+ *
+ * For active scanning on channels that have regulatory restrictions against
+ * blindly transmitting, the scan can listen before transmitting, to make sure
+ * that there is already legitimate activity on the channel.  If enough
+ * packets are cleanly received on the channel (controlled by good_CRC_th,
+ * typical value 1), the scan engine starts transmitting probe requests.
+ *
+ * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
+ *
+ * To avoid uCode errors, see timing restrictions described under
+ * struct iwl_scan_channel.

+ *
+ *****************************************************************************/
+
+/**
+ * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
+ *
+ * This command sets up the Rx signal detector for a sensitivity level that
+ * is high enough to lock onto all signals within the associated network,
+ * but low enough to ignore signals that are below a certain threshold, so as
+ * not to have too many "false alarms".  False alarms are signals that the
+ * Rx DSP tries to lock onto, but then discards after determining that they
+ * are noise.
+ *
+ * The optimum number of false alarms is between 5 and 50 per 200 TUs
+ * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
+ * time listening, not transmitting).  Driver must adjust sensitivity so that
+ * the ratio of actual false alarms to actual Rx time falls within this range.
+ *
+ * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
+ * received beacon.  These provide information to the driver to analyze the
+ * sensitivity.  Don't analyze statistics that come in from scanning, or any
+ * other non-associated-network source.  Pertinent statistics include:
+ *
+ * From "general" statistics (struct statistics_rx_non_phy):
+ *
+ * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
+ *   Measure of energy of desired signal.  Used for establishing a level
+ *   below which the device does not detect signals.
+ *
+ * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
+ *   Measure of background noise in silent period after beacon.
+ *
+ * channel_load
+ *   uSecs of actual Rx time during beacon period (varies according to
+ *   how much time was spent transmitting).
+ *
+ * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
+ *
+ * false_alarm_cnt
+ *   Signal locks abandoned early (before phy-level header).
+ *
+ * plcp_err
+ *   Signal locks abandoned late (during phy-level header).
+ *
+ * NOTE:  Both false_alarm_cnt and plcp_err increment monotonically from
+ *        beacon to beacon, i.e. each value is an accumulation of all errors
+ *        before and including the latest beacon.  Values will wrap around to 0
+ *        after counting up to 2^32 - 1.  Driver must differentiate vs.
+ *        previous beacon's values to determine # false alarms in the current
+ *        beacon period.
+ *
+ * Total number of false alarms = false_alarms + plcp_errs
+ *
+ * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
+ * (notice that the start points for OFDM are at or close to settings for
+ * maximum sensitivity):
+ *
+ *                                             START  /  MIN  /  MAX
+ *   HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX          90   /   85  /  120
+ *   HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX     170   /  170  /  210
+ *   HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX         105   /  105  /  140
+ *   HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX     220   /  220  /  270
+ *
+ *   If actual rate of OFDM false alarms (+ plcp_errors) is too high
+ *   (greater than 50 for each 204.8 msecs listening), reduce sensitivity
+ *   by *adding* 1 to all 4 of the table entries above, up to the max for
+ *   each entry.  Conversely, if false alarm rate is too low (less than 5
+ *   for each 204.8 msecs listening), *subtract* 1 from each entry to
+ *   increase sensitivity.
+ *
+ * For CCK sensitivity, keep track of the following:
+ *
+ *   1).  20-beacon history of maximum background noise, indicated by
+ *        (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
+ *        3 receivers.  For any given beacon, the "silence reference" is
+ *        the maximum of last 60 samples (20 beacons * 3 receivers).
+ *
+ *   2).  10-beacon history of strongest signal level, as indicated
+ *        by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
+ *        i.e. the strength of the signal through the best receiver at the
+ *        moment.  These measurements are "upside down", with lower values
+ *        for stronger signals, so max energy will be *minimum* value.
+ *
+ *        Then for any given beacon, the driver must determine the *weakest*
+ *        of the strongest signals; this is the minimum level that needs to be
+ *        successfully detected, when using the best receiver at the moment.
+ *        "Max cck energy" is the maximum (higher value means lower energy!)
+ *        of the last 10 minima.  Once this is determined, driver must add
+ *        a little margin by adding "6" to it.
+ *
+ *   3).  Number of consecutive beacon periods with too few false alarms.
+ *        Reset this to 0 at the first beacon period that falls within the
+ *        "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
+ *
+ * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
+ * (notice that the start points for CCK are at maximum sensitivity):
+ *
+ *                                             START  /  MIN  /  MAX
+ *   HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX         125   /  125  /  200
+ *   HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX     200   /  200  /  400
+ *   HD_MIN_ENERGY_CCK_DET_INDEX                100   /    0  /  100
+ *
+ *   If actual rate of CCK false alarms (+ plcp_errors) is too high
+ *   (greater than 50 for each 204.8 msecs listening), method for reducing
+ *   sensitivity is:
+ *
+ *   1)  *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
+ *       up to max 400.
+ *
+ *   2)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
+ *       sensitivity has been reduced a significant amount; bring it up to
+ *       a moderate 161.  Otherwise, *add* 3, up to max 200.
+ *
+ *   3)  a)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
+ *       sensitivity has been reduced only a moderate or small amount;
+ *       *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
+ *       down to min 0.  Otherwise (if gain has been significantly reduced),
+ *       don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
+ *
+ *       b)  Save a snapshot of the "silence reference".
+ *
+ *   If actual rate of CCK false alarms (+ plcp_errors) is too low
+ *   (less than 5 for each 204.8 msecs listening), method for increasing
+ *   sensitivity is used only if:
+ *
+ *   1a)  Previous beacon did not have too many false alarms
+ *   1b)  AND difference between previous "silence reference" and current
+ *        "silence reference" (prev - current) is 2 or more,
+ *   OR 2)  100 or more consecutive beacon periods have had rate of
+ *          less than 5 false alarms per 204.8 milliseconds rx time.
+ *
+ *   Method for increasing sensitivity:
+ *
+ *   1)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
+ *       down to min 125.
+ *
+ *   2)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
+ *       down to min 200.
+ *
+ *   3)  *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
+ *
+ *   If actual rate of CCK false alarms (+ plcp_errors) is within good range
+ *   (between 5 and 50 for each 204.8 msecs listening):
+ *
+ *   1)  Save a snapshot of the silence reference.
+ *
+ *   2)  If previous beacon had too many CCK false alarms (+ plcp_errors),
+ *       give some extra margin to energy threshold by *subtracting* 8
+ *       from value in HD_MIN_ENERGY_CCK_DET_INDEX.
+ *
+ *   For all cases (too few, too many, good range), make sure that the CCK
+ *   detection threshold (energy) is below the energy level for robust
+ *   detection over the past 10 beacon periods, the "Max cck energy".
+ *   Lower values mean higher energy; this means making sure that the value
+ *   in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

+ * REPLY_PHY_CALIBRATION_CMD = 0xb0 (command, has simple generic response)
+ *
+ * This command sets the relative gains of 4965 device's 3 radio receiver chains.
+ *
+ * After the first association, driver should accumulate signal and noise
+ * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20
+ * beacons from the associated network (don't collect statistics that come
+ * in from scanning, or any other non-network source).
+ *
+ * DISCONNECTED ANTENNA:
+ *
+ * Driver should determine which antennas are actually connected, by comparing
+ * average beacon signal levels for the 3 Rx chains.  Accumulate (add) the
+ * following values over 20 beacons, one accumulator for each of the chains
+ * a/b/c, from struct statistics_rx_non_phy:
+ *
+ * beacon_rssi_[abc] & 0x0FF (unsigned, units in dB)
+ *
+ * Find the strongest signal from among a/b/c.  Compare the other two to the
+ * strongest.  If any signal is more than 15 dB (times 20, unless you
+ * divide the accumulated values by 20) below the strongest, the driver
+ * considers that antenna to be disconnected, and should not try to use that
+ * antenna/chain for Rx or Tx.  If both A and B seem to be disconnected,
+ * driver should declare the stronger one as connected, and attempt to use it
+ * (A and B are the only 2 Tx chains!).
+ *
+ *
+ * RX BALANCE:
+ *
+ * Driver should balance the 3 receivers (but just the ones that are connected
+ * to antennas, see above) for gain, by comparing the average signal levels
+ * detected during the silence after each beacon (background noise).
+ * Accumulate (add) the following values over 20 beacons, one accumulator for
+ * each of the chains a/b/c, from struct statistics_rx_non_phy:
+ *
+ * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
+ *
+ * Find the weakest background noise level from among a/b/c.  This Rx chain
+ * will be the reference, with 0 gain adjustment.  Attenuate other channels by
+ * finding noise difference:
+ *
+ * (accum_noise[i] - accum_noise[reference]) / 30
+ *
+ * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
+ * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
+ * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
+ * and set bit 2 to indicate "reduce gain".  The value for the reference
+ * (weakest) chain should be "0".
+ *
+ * diff_gain_[abc] bit fields:
+ *   2: (1) reduce gain, (0) increase gain

+ * it has a supported API version. The firmware's API version will be

+ * on firmware version used.
+ *
+ * For example,

+ *	Driver interacts with Firmware API version >= 2.
+ * } else {
+ *	Driver interacts with Firmware API version 1.
+ * }

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwlegacy_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel.  We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware.  This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel.  There is no corresponding channel information for that
+ * entry.

+ *     (RBs) have been filled, via a "write pointer", actually the index of
+ *     the RB's corresponding RBD within the circular buffer.  Driver sets

+ *     11- 0:  Index of last filled Rx buffer descriptor
+ *             (4965 writes, driver reads this value)
+ *
+ * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
+ * enter pointers to these RBs into contiguous RBD circular buffer entries,
+ * and update the 4965's "write" index register,
+ * FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
+ *
+ * This "write" index corresponds to the *next* RBD that the driver will make
+ * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
+ * the circular buffer.  This value should initially be 0 (before preparing any
+ * RBs), should be 8 after preparing the first 8 RBs (for example), and must
+ * wrap back to 0 at the end of the circular buffer (but don't wrap before
+ * "read" index has advanced past 1!  See below).
+ * NOTE:  4965 EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
+ *
+ * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
+ * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
+ * to tell the driver the index of the latest filled RBD.  The driver must
+ * read this "read" index from DRAM after receiving an Rx interrupt from 4965.
+ *
+ * The driver must also internally keep track of a third index, which is the
+ * next RBD to process.  When receiving an Rx interrupt, driver should process
+ * all filled but unprocessed RBs up to, but not including, the RB
+ * corresponding to the "read" index.  For example, if "read" index becomes "1",
+ * driver may process the RB pointed to by RBD 0.  Depending on volume of
+ * traffic, there may be many RBs to process.
+ *
+ * If read index == write index, 4965 thinks there is no room to put new data.
+ * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
+ * be safe, make sure that there is a gap of at least 2 RBDs between "write"
+ * and "read" indexes; that is, make sure that there are no more than 254
+ * buffers waiting to be filled.

+/**
+ * BSM (Bootstrap State Machine)
+ *
+ * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
+ * in special SRAM that does not power down when the embedded control
+ * processor is sleeping (e.g. for periodic power-saving shutdowns of radio).
+ *
+ * When powering back up after sleeps (or during initial uCode load), the BSM
+ * internally loads the short bootstrap program from the special SRAM into the
+ * embedded processor's instruction SRAM, and starts the processor so it runs
+ * the bootstrap program.
+ *
+ * This bootstrap program loads (via PCI busmaster DMA) instructions and data
+ * images for a uCode program from host DRAM locations.  The host driver
+ * indicates DRAM locations and sizes for instruction and data images via the
+ * four BSM_DRAM_* registers.  Once the bootstrap program loads the new program,
+ * the new program starts automatically.
+ *
+ * The uCode used for open-source drivers includes two programs:
+ *
+ * 1)  Initialization -- performs hardware calibration and sets up some
+ *     internal data, then notifies host via "initialize alive" notification
+ *     (struct iwl_init_alive_resp) that it has completed all of its work.
+ *     After signal from host, it then loads and starts the runtime program.
+ *     The initialization program must be used when initially setting up the
+ *     NIC after loading the driver.
+ *
+ * 2)  Runtime/Protocol -- performs all normal runtime operations.  This
+ *     notifies host via "alive" notification (struct iwl_alive_resp) that it
+ *     is ready to be used.
+ *
+ * When initializing the NIC, the host driver does the following procedure:
+ *
+ * 1)  Load bootstrap program (instructions only, no data image for bootstrap)
+ *     into bootstrap memory.  Use dword writes starting at BSM_SRAM_LOWER_BOUND
+ *
+ * 2)  Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction
+ *     images in host DRAM.
+ *
+ * 3)  Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked:
+ *     BSM_WR_MEM_SRC_REG = 0
+ *     BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND
+ *     BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image
+ *
+ * 4)  Load bootstrap into instruction SRAM:
+ *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START
+ *
+ * 5)  Wait for load completion:
+ *     Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0
+ *
+ * 6)  Enable future boot loads whenever NIC's power management triggers it:
+ *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN
+ *
+ * 7)  Start the NIC by removing all reset bits:
+ *     CSR_RESET = 0
+ *
+ *     The bootstrap uCode (already in instruction SRAM) loads initialization
+ *     uCode.  Initialization uCode performs data initialization, sends
+ *     "initialize alive" notification to host, and waits for a signal from
+ *     host to load runtime code.
+ *
+ * 4)  Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction
+ *     images in host DRAM.  The last register loaded must be the instruction
+ *     byte count register ("1" in MSbit tells initialization uCode to load
+ *     the runtime uCode):
+ *     BSM_DRAM_INST_BYTECOUNT_REG = byte count | BSM_DRAM_INST_LOAD
+ *
+ * 5)  Wait for "alive" notification, then issue normal runtime commands.
+ *
+ * Data caching during power-downs:
+ *
+ * Just before the embedded controller powers down (e.g for automatic
+ * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA)
+ * a current snapshot of the embedded processor's data SRAM into host DRAM.
+ * This caches the data while the embedded processor's memory is powered down.
+ * Location and size are controlled by BSM_DRAM_DATA_* registers.
+ *
+ * NOTE:  Instruction SRAM does not need to be saved, since that doesn't
+ *        change during operation; the original image (from uCode distribution
+ *        file) can be used for reload.
+ *
+ * When powering back up, the BSM loads the bootstrap program.  Bootstrap looks
+ * at the BSM_DRAM_* registers, which now point to the runtime instruction
+ * image and the cached (modified) runtime data (*not* the initialization
+ * uCode).  Bootstrap reloads these runtime images into SRAM, and restarts the
+ * uCode from where it left off before the power-down.
+ *
+ * NOTE:  Initialization uCode does *not* run as part of the save/restore
+ *        procedure.
+ *
+ * This save/restore method is mostly for autonomous power management during
+ * normal operation (result of POWER_TABLE_CMD).  Platform suspend/resume and
+ * RFKILL should use complete restarts (with total re-initialization) of uCode,
+ * allowing total shutdown (including BSM memory).
+ *
+ * Note that, during normal operation, the host DRAM that held the initial
+ * startup data for the runtime code is now being used as a backup data cache
+ * for modified data!  If you need to completely re-initialize the NIC, make
+ * sure that you use the runtime data image from the uCode distribution file,
+ * not the modified/saved runtime data.  You may want to store a separate
+ * "clean" runtime data image in DRAM to avoid disk reads of distribution file.

+/**
+ * Tx Scheduler
+ *
+ * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
+ * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
+ * host DRAM.  It steers each frame's Tx command (which contains the frame
+ * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
+ * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
+ * but one DMA channel may take input from several queues.
+ *
+ * Tx DMA FIFOs have dedicated purposes.  For 4965, they are used as follows
+ * (cf. default_queue_to_tx_fifo in iwl-4965.c):
+ *
+ * 0 -- EDCA BK (background) frames, lowest priority
+ * 1 -- EDCA BE (best effort) frames, normal priority
+ * 2 -- EDCA VI (video) frames, higher priority
+ * 3 -- EDCA VO (voice) and management frames, highest priority
+ * 4 -- Commands (e.g. RXON, etc.)
+ * 5 -- unused (HCCA)
+ * 6 -- unused (HCCA)
+ * 7 -- not used by driver (device-internal only)
+ *
+ *
+ * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
+ * In addition, driver can map the remaining queues to Tx DMA/FIFO
+ * channels 0-3 to support 11n aggregation via EDCA DMA channels.
+ *
+ * The driver sets up each queue to work in one of two modes:
+ *
+ * 1)  Scheduler-Ack, in which the scheduler automatically supports a
+ *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
+ *     contains TFDs for a unique combination of Recipient Address (RA)
+ *     and Traffic Identifier (TID), that is, traffic of a given
+ *     Quality-Of-Service (QOS) priority, destined for a single station.
+ *
+ *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
+ *     each frame within the BA window, including whether it's been transmitted,
+ *     and whether it's been acknowledged by the receiving station.  The device
+ *     automatically processes block-acks received from the receiving STA,
+ *     and reschedules un-acked frames to be retransmitted (successful
+ *     Tx completion may end up being out-of-order).
+ *
+ *     The driver must maintain the queue's Byte Count table in host DRAM
+ *     (struct iwl4965_sched_queue_byte_cnt_tbl) for this mode.
+ *     This mode does not support fragmentation.
+ *
+ * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
+ *     The device may automatically retry Tx, but will retry only one frame
+ *     at a time, until receiving ACK from receiving station, or reaching
+ *     retry limit and giving up.
+ *
+ *     The command queue (#4/#9) must use this mode!
+ *     This mode does not require use of the Byte Count table in host DRAM.
+ *
+ * Driver controls scheduler operation via 3 means:
+ * 1)  Scheduler registers
+ * 2)  Shared scheduler data base in internal 4956 SRAM
+ * 3)  Shared data in host DRAM
+ *
+ * Initialization:
+ *
+ * When loading, driver should allocate memory for:
+ * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
+ * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
+ *     (1024 bytes for each queue).
+ *
+ * After receiving "Alive" response from uCode, driver must initialize
+ * the scheduler (especially for queue #4/#9, the command queue, otherwise
+ * the driver can't issue commands!):
+ */
+
+/**
+ * Max Tx window size is the max number of contiguous TFDs that the scheduler
+ * can keep track of at one time when creating block-ack chains of frames.
+ * Note that "64" matches the number of ack bits in a block-ack packet.
+ * Driver should use SCD_WIN_SIZE and SCD_FRAME_LIMIT values to initialize
+ * IWL49_SCD_CONTEXT_QUEUE_OFFSET(x) values.

+/************************** RX-FUNCTIONS ****************************/
+/*
+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC.  These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC.  The driver and NIC manage the Rx buffers by means
+ * of indexes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ index
+ * and fire the RX interrupt.  The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replenish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ *   detached from the iwl->rxq.  The driver 'processed' index is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
+ *   were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * iwl_legacy_rx_queue_alloc()   Allocates rx_free
+ * iwl_rx_replenish()     Replenishes rx_free list from rx_used, and calls
+ *                            iwl_rx_queue_restock
+ * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
+ *                            queue, updates firmware pointers, and updates
+ *                            the WRITE index.  If insufficient rx_free buffers
+ *                            are available, schedules iwl_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - iwl_rx()         Detach iwl_rx_mem_buffers from pool up to the
+ *                            READ INDEX, detaching the SKB from the pool.
+ *                            Moves the packet buffer from queue to rx_used.
+ *                            Calls iwl_rx_queue_restock to refill any empty
+ *                            slots.

+ * Theory of operation
+ *
+ * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
+ * of buffer descriptors, each of which points to one or more data buffers for
+ * the device to read from or fill.  Driver and device exchange status of each
+ * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
+ * entries in each circular buffer, to protect against confusing empty and full
+ * queue states.
+ *
+ * The device reads or writes the data in the queues via the device's several
+ * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.

+   CHOKe stateless AQM for fair bandwidth allocation
+   =================================================
+
+   CHOKe (CHOose and Keep for responsive flows, CHOose and Kill for
+   unresponsive flows) is a variant of RED that penalizes misbehaving flows but
+   maintains no flow state. The difference from RED is an additional step
+   during the enqueuing process. If average queue size is over the
+   low threshold (qmin), a packet is chosen at random from the queue.
+   If both the new and chosen packet are from the same flow, both
+   are dropped. Unlike RED, CHOKe is not really a "classful" qdisc because it
+   needs to access packets in queue randomly. It has a minimal class
+   interface to allow overriding the builtin flow classifier with
+   filters.
+
