This diff adds 11n support to the athn(4) driver.
Requires -current net80211 code from today.
Tested in hostap mode and client mode with:
athn0 at pci1 dev 0 function 0 "Atheros AR9281" rev 0x01: apic 2 int 16
athn0: AR9280 rev 2 (2T2R), ROM rev 22, adddress xx:xx:xx:xx:xx:xx
And in client mode with:
athn0 at uhub1 port 2 configuration 1 interface 0 "ATHEROS USB2.0 WLAN" rev
2.00/1.08 addr 2
athn0: AR9271 rev 1 (1T1R), ROM rev 13, address xx:xx:xx:xx:xx:xx
Hostap performance is not perfect yet but should be no worse than
11a/b/g modes in the same environment.
For Linux clients a fix for WME params is needed which I also posted to tech@.
This diff does not modify the known-broken and disabled ar9003 code,
apart from making sure it still builds.
I'm looking for both tests and OKs.
