[PATCH 1/3] qtnfmac: handle channel switch events for connected stations only

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Channel switch events from firmware should be processed only when STA
is already connected to BSS. On connect this notification is not needed
since full BSS info will be supplied by cfg80211_connect_result.
