Subject: iwlwifi: mvm: Change beacon filter enablement condition
From: Alexander Bondar <alexander.bondar@xxxxxxxxx>
commit c63722cfd441bd3a99c65fa4c40bc65d7776e772 upstream.
Enable beacon filter only if at least one beacon from candidate
AP is received before or after association. Check this condition before
enabling BF upon secured association completion. Add BF enablement to
mac80211 event that indicates beacon is received after association.
Too early beacon filtering enablement can lead to disconnection due to
missing AP's beacon after association.
