net80211. It was especially important to zero the IEEE80211_F_DROPUNENC (discard unencrypted packets) flag in operating modes where the firmware decrypts for us. Otherwise, the 802.11 layer discarded all received frames. See wi_mend_flags. From FreeBSD, with improvements by me. For better compliance with the "net80211 way": set sc_cnfauthmode from ic->ic_bss->ni_authmode. Enter the RUN state through ieee80211_create_ibss instead of ieee80211_new_state(IEEE80211_S_RUN). To sync BSSID in ad hoc mode, use ieee80211_sta_join() instead of ieee80211_new_state(IEEE80211_S_RUN). From FreeBSD. Configure the firmware to obey IEEE80211_F_DROPUNENC. As we change to state RUN in STA mode, generate a link-status message on the routing socket with a call to ieee80211_notify_node_join() instead of calling rt_ifmsg directly. Run normal net80211 processing (ieee80211_newstate) on the ->RUN transition.
