3.19.8-ckt4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Kazior <michal.kazior@xxxxxxxxx>
commit 6fcafef7363bec35ddf148abae6e879e27771eb0 upstream.
If htt.freq isn't cleared and contains garbage fw
may discard tx packets. Prevent this from
happening by clearing htt.freq properly.
Possible manifestation of the problem could be not
being able to send auth request/response frames on
firmware with HTT >= 3.4 (when freq param was
introduced), e.g. on qca6174.
Fixes: 8d6d36243610 ("ath10k: fix offchan reliability")
