+Subject: ath10k: fix incorrect multicast/broadcast rate setting
+
+Invalid rate code is sent to firmware when multicast rate value of 0 is
+sent to driver indicating disabled case, causing broken mesh path.
+so fix that.
+
+Tested on QCA9984 with firmware 10.4-3.6.1-00827
+
+Fixes: cd93b83ad92 ("ath10k: support for multicast rate control")
