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).
|
||
|
|
|
||
|
|
Fixes: db90c243a0b9 ("mac80211: update to version based on 4.19-rc4")

|

|
|
+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")
