From: Sven Eckelmann Date: Mon, 25 Feb 2019 20:42:28 +0100 Subject: mac80211: ath10k: fix incorrect multicast/broadcast rate setting If no mcast_rate is set for the wifi-iface then there is no rate_idx (0) set for the bss. This breaks for example 5GHz meshpoint interfaces because 0 maps to a CCK rate (11Mbit/s).
