[heads up] please test -HEAD ath(4) 802.11n!

[Adrian Chadd]

Hi all,

I've just done some major surgery to the ath(4) TX path to fix TX
throughput issues on SMP. The commit history has all the sordid
details.

I'd really appreciate it if people could test this out in STA and AP
mode with INVARIANTS/WITNESS enabled. I'd like to ensure I haven't
introduced LORs or any locking issues.

As always, positive feedback is also useful (just so I know the code is tested.)

I'd really like to get this thrashed out so I can move onto
implementing the management frame prioritisation, power save and
filtered frame support. Once that's done, I'll enable 802.11n by
default.

Thanks again!




Adrian
