main.c contains the following as in the patches that you posted:

hw->flags = IEEE80211_HW_SIGNAL_DBM |
		    IEEE80211_HW_SUPPORTS_PS |
		    IEEE80211_HW_SUPPORTS_DYNAMIC_PS |
		    IEEE80211_HW_REPORTS_TX_ACK_STATUS |
		    IEEE80211_HW_SUPPORTS_UAPSD |
		    IEEE80211_HW_CONNECTION_MONITOR |
		    IEEE80211_HW_NEED_DTIM_PERIOD;

IEEE80211_HW_BEACON_FILTER does not seem to be defined anywhere in the
header files.  Do I need this?

I am using SDIO IRQ.


Thanks,
