Subject: [PATCH] mt76: mt7915: set bssinfo/starec command when adding interface
Git-commit: d3bc111307447a2a4fa2d276ce75530732c29358
Patch-mainline: v5.18-rc1
References: bsc#1209980
bssinfo/starec disabled commands are sent during removing interface.
However, if we don't set corresponding enabled commands before
removing interface, the fw may enter an exception state due to
some NULL structs.
For example, the following commands can cause fw timeout in our newer
Chips: ifconfig wlan0/mon0 up ifconfig wlan0/mon0 down
Fix this by setting enabled commands once interface added.
