This took an embarrasingly long time to find. The state changes for a radio with a STA /and/ AP VAP gets a bit messy. The AP maps are marked as waiting, waiting for the STA AP to find a channel to use before the AP VAPs become active. However, the code path that clears the OACTIVE flag on a VAP only runs during a successful run of ieee80211_newstate_cb(). So here is how it goes: * the STA VAP goes down and needs to scan; * the AP vap goes RUN->INIT; but it doesn't YET call ieee80211_newstate_cb(); * meanwhile - a send on the AP VAP causes the VAP to set the OACTIVE flag here; * then the STA VAP finishes scan and goes to RUN; * which will call wakeupwaiting() as part of the STA VAP transition to RUN; * .. then the AP VAP goes INIT->RUN directly via a call to hostap_newstate in wakeupwaiting rather than it being through the deferred path; * /then/ the ieee80211_newstate_cb() is called, but it sees the state go RUN->RUN; * .. which results in the OACTIVE flag never being cleared. This clears the OACTIVE flag when a VAP transitions RUN->RUN; the driver layer or net80211 layer can set it if required in a subsequent transmit.
