commit cd93b83ad927b2c7979e0add0343ace59328b461
Author: Pradeep Kumar Chitrapu <pradeepc@codeaurora.org>
Date: Wed Jul 25 10:59:39 2018 +0300
ath10k: support for multicast rate control
Issues a wmi command to firmware when multicast rate change is received with the
new BSS_CHANGED_MCAST_RATE flag. Also fixes the incorrect fixed_rate setting
for CCK rates which got introduced with addition of ath10k_rates_rev2 enum.
Tested on QCA9984 with firmware ver 10.4-3.6-00104
