+Subject: [PATCH] mac80211: Fix Public Action frame RX in AP mode
+
+Public Action frames use special rules for how the BSSID field (Address
+3) is set. A wildcard BSSID is used in cases where the transmitter and
+recipient are not members of the same BSS. As such, we need to accept
+Public Action frames with wildcard BSSID.
+
+Commit db8e17324553 ("mac80211: ignore frames between TDLS peers when
+operating as AP") added a rule that drops Action frames to TDLS-peers
+based on an Action frame having different DA (Address 1) and BSSID
+(Address 3) values. This is not correct since it misses the possibility
+of BSSID being a wildcard BSSID in which case the Address 1 would not
+necessarily match.
+
+Fix this by allowing mac80211 to accept wildcard BSSID in an Action
+frame when in AP mode.
+
+Fixes: db8e17324553 ("mac80211: ignore frames between TDLS peers when operating as AP")

+ header
+
+The MCS bandwidth part of the radiotap header is 2 bits wide. The full 2
+bit have to compared against IEEE80211_RADIOTAP_MCS_BW_40 and not only if
+the first bit is set. Otherwise IEEE80211_RADIOTAP_MCS_BW_40 can be
+confused with IEEE80211_RADIOTAP_MCS_BW_20U.
