Subject: mac80211: clear sta.drv_priv on reconfiguration

drivers might assume sta.drv_priv is clear while
the sta is added, so clear it on reconfinguration.

Subject: cfg80211/mac80211: move information element parsing logic to cfg80211

Moving the parsing logic for retrieving the information elements
stored in management frames, e.g. beacons or probe responses,
and making it available to other cfg80211 drivers.

Subject: mac80211: Remove unnecessary OOM logging messages

Removing unnecessary messages saves code and text.

Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

Subject: mac80211: Send the management frame at requested rate

Whenever the scan request or tx_mgmt is requesting not to
use CCK rate for managemet frames through
NL80211_ATTR_TX_NO_CCK_RATE attribute, then mac80211 should
select appropriate least non-CCK rate. This could help to
send P2P probes and P2P action frames at non 11b rates
without diabling 11b rates globally.

Subject: mac80211: remove return value from add_pending_skbs

Now that we no longer use the return value, we no
longer need to maintain it either, so remove it.

Subject: mac80211: optimise station flags

The flaglock in struct sta_info has long been
something that I wanted to get rid of, this
finally does the conversion to atomic bitops.

The conversion itself is straight-forward in
most places, a few things needed to change a
bit since we can no longer use multiple bits
at the same time.

On x86-64, this is a fairly significant code
size reduction:
   text	   data	    bss	    dec	    hex
 427861	  23648	   1008	 452517	  6e7a5	before
 425383	  23648	    976	 450007	  6ddd7	after

Subject: net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.
