WoW hasn't been tested or verified with ath9k using AR9280 at all, so we don't know what is missing in ath9k to handle the chip's peculiarities. > I'm asking because, we have RHEL customer that request WoWLAN support > for AR9280.

If AR9280 is used, getting support for WoW would be difficult. AR9462 has been through internal test-cycles for WoW, so it seems a more sensible choice. But, the AR9002-specific code can be retained in the driver if RH needs it. Sujith
