+    mac80211: fix possible NULL dereference
+    
+    If chanctx is missing on a given vif then the band
+    is assumed to be 2GHz. However if hw doesn't
+    support 2GHz band then mac80211 ended up with a
+    NULL dereference.
+    
+    This fixes a splat:
+    
+    [ 4605.207223] BUG: unable to handle kernel NULL pointer dereference at 0000000000000018
+    [ 4605.210789] IP: [<ffffffffa07b5635>] ieee80211_parse_bitrates+0x65/0x110 [mac80211]
+    
+    The splat was preceeded by WARN_ON(!chanctx_conf)
+    in ieee80211_get_sdata_band().

+    mac80211: fix WPA with VLAN on AP side with ps-sta again
+    
+    commit de74a1d9032f4d37ea453ad2a647e1aff4cd2591
+      "mac80211: fix WPA with VLAN on AP side with ps-sta"
+    fixed an issue where queued multicast packets would
+    be sent out encrypted with the key of an other bss.
+    
+    commit "7cbf9d017dbb5e3276de7d527925d42d4c11e732"
+      "mac80211: fix oops on mesh PS broadcast forwarding"
+    essentially reverted it, because vif.type cannot be AP_VLAN
+    due to the check to vif.type in ieee80211_get_buffered_bc before.
+    
+    As the later commit intended to fix the MESH case, fix it
+    by checking for IFTYPE_AP instead of IFTYPE_AP_VLAN.
+

+    cfg80211: remove racy beacon_interval assignment
+    
+    In case of AP mode, the beacon interval is already reset to
+    zero inside cfg80211_stop_ap(), and in the other modes it
+    isn't relevant. Remove the assignment to remove a potential
+    race since the assignment isn't properly locked.
