[PATCH v2] wifi: mac80211: restore non-chanctx injection behaviour

by Johannes Berg

From: Johannes Berg <johannes.berg(a)intel.com> During the transition to use channel contexts throughout, the ability to do injection while in monitor mode concurrent with another interface was lost, since the (virtual) monitor won't have a chanctx assigned in this scenario. We could use the local->hw.conf.chandef in the emulation case, but that wouldn't fix drivers (such as mt76) that themselves are now using channel contexts. So instead, assume that if there's just a single chanctx that must be the one meant for injection, addressing both cases.
