3c*/acenic/typhoon: Move 3Com Ethernet drivers
Moves the 3Com drivers into drivers/net/ethernet/3com/ and the necessary Kconfig and Makefile changes. Did not move the following drivers becuase they use a non-3Com chipset: 3c503, 3c505, 3c507, 3c523 and 3c527 CC: Steffen Klassert <klassert@mathematik.tu-chemnitz.de> CC: David Dillow <dave@thedillows.org> CC: Jes Sorensen <jes@trained-monkey.org> CC: Alan Cox <alan@linux.intel.com> CC: David Hinds <dahinds@users.sourceforge.net> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Acked-by: David Dillow <dave@thedillows.org>

-/* 3c574.c: A PCMCIA ethernet driver for the 3com 3c574 "RoadRunner".
-

- Donald Becker, becker@scyld.com, (driver core) and

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
-Adapter.
-
-II. Board-specific settings
-
-None -- PC cards are autoconfigured.
-
-III. Driver operation
-
-The 3c574 uses a Boomerang-style interface, without the bus-master capability.
-See the Boomerang driver and documentation for most details.
-
-IV. Notes and chip documentation.
-
-Two added registers are used to enhance PIO performance, RunnerRdCtrl and
-RunnerWrCtrl. These are 11 bit down-counters that are preloaded with the
-count of word (16 bits) reads or writes the driver is about to do to the Rx
-or Tx FIFO. The chip is then able to hide the internal-PCI-bus to PC-card
-translation latency by buffering the I/O operations with an 8 word FIFO.
-Note: No other chip accesses are permitted when this buffer is used.
-
-A second enhancement is that both attribute and common memory space
-0x0800-0x0fff can translated to the PIO FIFO. Thus memory operations (faster
-with *some* PCcard bridges) may be used instead of I/O operations.
-This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
-
-Some slow PC card bridges work better if they never see a WAIT signal.
-This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
-Only do this after testing that it is reliable and improves performance.
-
-The upper five bits of RunnerRdCtrl are used to window into PCcard
-configuration space registers. Window 0 is the regular Boomerang/Odie
-register set, 1-5 are various PC card control registers, and 16-31 are
-the (reversed!) CIS table.
-
-A final note: writing the InternalConfig register in window 3 with an
-invalid ramWidth is Very Bad.
-
