+Subject: [PATCH] wifi: ieee80211: correctly mark FTM frames non-bufferable
+
+The checks of whether or not a frame is bufferable were not
+taking into account that some action frames aren't, such as
+FTM. Check this, which requires some changes to the function
+ieee80211_is_bufferable_mmpdu() since we need the whole skb
+for the checks now.

+Subject: [PATCH] wifi: mac80211: flush queues on STA removal
+
+When we remove a station, we first make it unreachable,
+then we (must) remove its keys, and then remove the
+station itself. Depending on the hardware design, if
+we have hardware crypto at all, frames still sitting
+on hardware queues may then be transmitted without a
+valid key, possibly unencrypted or with a fixed key.
+
+Fix this by flushing the queues when removing stations
+so this cannot happen.
