Subject: [PATCH] mt76: mt76x02u: enable multi-vif support
Git-commit: f110d1d51d12c6d179eda6e53b23a4af1959aefa
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
Enable multi-interface support for mt76x02u driver. For the moment
allow max two concurrent interfaces in order to preserve enough room
for ps traffic since we are using beacon slots for it.
I have successfully tested the following configuration:
- AP + STA
- AP0 + AP1
