Hi all,
We meet some problem when try P2P by using ath9k_htc compat-wireless-v3.6.8-1.
When using the compat-wireless-v3.6.8-1, AR9271 could find other P2P devices, but other P2P devices couldn't find AR9271 (runs ath9k_htc) because driver couldn't report Probe Request to wpa_supplicant.
And this issue could not be observed when using compat-wireless-v3.0.9-1, by compare with compat-wireless-v3.0.9-1, ATH9K RX filter is ?set correctly after got "Report Probe Request" command from wpa_supplicant, but ATH9K driver couldn't get "Probe Request" frame(I add debug msg in ieee80211_rx_handlers() function).

Did you confirm ath9k_htc is handing over probe requests to mac80211?
Might be useful to add debugging in prepare_for_handlers() instead.
