Hi all,
can somebody please explain in some more details this possibility of
ath9k driver, mentioned here: and
specially here: in these
patches signed-off by Jouni.

Does this means that ath9k devices can be put in AP and STA modes
simultaneously (one virtual interface for each) over different

I am looking to solve this problem: I want to have always present AP
for user settings that I bring on boot, so I give it some
pre-configured channel. Via this AP user will configure other
interface in STA mode to connect to home network. However, this home
network can be over any channel, very potentially different of the one
I have chosen for AP.

Would these patches allow something like this, and how they should be
used (I saw here some use case - at,
but not clear enough)?

Best regards,
