From 6fcafef7363bec35ddf148abae6e879e27771eb0 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Mon, 30 Mar 2015 09:51:51 +0300 Subject: [PATCH] ath10k: clear htt.freq 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.
