Hi,I am looking to upgrade my current nodes and AP from the AR9280 2x2 MIMO NIC to the AR9380 3x3 NIC.
Thus I was wondering if someone can kindly comment on the current chipset stability with ath9k, also the current supported features (e.g. ?"iw list" output) such as setting the NIC as an AP/Master using hostapd, Greenfield mode, TxBF, CSI info, and LPDC as well as rates achieved.
Thanks in advance -

Both are stable in our testing (virtual stations, AP mode), but we're having
a hard time sourcing AR9380 3x3 NICs..getting ship-times in August, etc....
I don't have details on the other things you ask about.
I'd suggest getting a few NICs and trying them out in your environment.
Even if they have problems, there are folks actively working on it and
likely it can be fixed. And at least for our use with virtual stations & APs,
there is no other NIC that comes close to the features that Atheros offers.
Thanks,
Ben

I cut out the stuff about channels, as that seems to be highly
dependent on which source you get your NIC from and what country code
is programmed in.
This is using kernel 3.0-rc2 and the very latest (I just pulled)
iw.git. The NIC is not associated, all I did was modprobe ath9k.
