-Subject: [PATCH] mac80211: use more bits for ack_frame_id
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-It turns out that this wasn't a good idea, I hit a test failure in
-hwsim due to this. That particular failure was easily worked around,
-but it raised questions: if an AP needs to, for example, send action
-frames to each connected station, the current limit is nowhere near
-enough (especially if those stations are sleeping and the frames are
-queued for a while.)
-
-Shuffle around some bits to make more room for ack_frame_id to allow
-up to 8192 queued up frames, that's enough for queueing 4 frames to
-each connected station, even at the maximum of 2007 stations on a
-single AP.
-
-We take the bits from band (which currently only 2 but I leave 3 in
-case we add another band) and from the hw_queue, which can only need
-4 since it has a limit of 16 queues.
-
-Fixes: 6912daed05e1 ("mac80211: Shrink the size of ack_frame_id to make room for tx_time_est")
