-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.
