freebsd kernel with SKQ

Adrian Chadd 67397d396f Add in the (very!) optional glue to flip the 11n bits for if_ath.
There's still a lot of random issues to sort out with the radio side of
things and AMPDU RX handling (and completely missing AMPDU TX handling!)
but if people wish to give this a go and assist in debugging the
issues, they can define ATH_DO_11N to enable it.

I'm just re-iterating - this is here to allow people to assist in
further 11n development; it is not any indication that the 11n support
is complete and functional.

Important notes:

* This doesn't support 1-stream cards yet - (eg AR9285) - the various bits
  that negotiate TX/RX MCS don't know not to try >1 stream TX or negotiate
  1-stream RX; so don't enable 11n unless you've first taught the rate
  control module and the net80211 stack to negotiate 1-stream stuff;

* The only rate control module minimally 11n aware is ath_rate_sample;

* ath_rate_sample doesn't know about HT/40; so airtime will be incorrectly
  calculated;

* The AR9160 and AR9280 radio code is unreliable at the higher MCS rates for
  some reason; this will definitely impact 11n performance;

* AMPDU-TX isn't yet implemented;

* AMPDU-RX may be a bit buggy still and will definitely suffer from the
  radio unreliability mentioned above (ie, don't expect 150/300mbit
  RX just yet.)

This is the top level of the FreeBSD source directory.  This file
was last revised on:
$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel, the kernel-modules and the contents of /etc.  The ``world''
target should only be used in cases where the source tree has not
changed from the currently running version.  See:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.

The ``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process, documentation
for which can be found at:
   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
And in the config(8) man page.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you might need to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/<arch>/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file NOTES contains entries and documentation for all possible
devices, not just those commonly used.  It is the successor of the ancient
LINT file, but in contrast to LINT, it is not buildable as a kernel but a
pure reference and documentation file.
