- 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")
