Adrian Chadd 3ae723d459 Begin fleshing out the TX FIFO support.
* Add ATH_TXQ_FIRST() for easy tasting of what's on the list;
* Add an "axq_fifo_depth" for easy tracking of how deep the current
  FIFO is;
* Flesh out the handoff (mcast, hw) functions;
* Begin fleshing out a TX ISR proc, which tastes the TX status FIFO.

The legacy hardware stuffs the TX completion at the end of the final frame
descriptor (or final sub-frame when doing aggregate.)  So it's feasible
to do a per-TXQ drain and process, as the needed info is right there.

For EDMA hardware, there's a separate TX completion FIFO.  So the TX
process routine needs to read the single FIFO and then process the
frames in each hardware queue.

This makes it difficult to do a per-queue process, as you'll end up with
frames in the TX completion FIFO for a different TXQ to the one you've
passed to ath_tx_draintxq() or ath_tx_processq().

Testing:

I've tested the TX queue and TX completion code in hostap mode on an
AR9380.  Beacon frames successfully transmit and the completion routine
is called.  Occasional data frames end up in TXQ 1 and are also
successfully completed.

However, this requires some changes to the beacon code path as:

* The AR9380 beacon configuration API is now in TU/8, rather than
  TU;
* The AR9380 TX API requires the rate control is setup using a call
  to setup11nratescenario, rather than having the try0 series setup
  (rate/tries for the first series); so the beacon won't go out.

I'll follow this up with commits to the beacon code.

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.
