+Subject: [PATCH] nl80211: Ignore 4addr mode enabling error if it was already
+ enabled
+
+nl80211_set_4addr_mode() could fail when trying to enable 4addr mode on
+an interface that is in a bridge and has 4addr mode already enabled.
+This operation would not have been necessary in the first place and this
+failure results in disconnecting, e.g., when roaming from one backhaul
+BSS to another BSS with Multi AP.
+
+Avoid this issue by ignoring the nl80211 command failure in the case
+where 4addr mode is being enabled while it has already been enabled.
