[PATCH 21/21] wifi: mac80211: mlme: refactor ieee80211_set_associated()

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

 



From: Johannes Berg <johannes.berg@xxxxxxxxx>

Split out much of the code in ieee80211_set_associated()
into a new ieee80211_link_set_associated() which can be
called per link later for MLO.
