Subject: [PATCH] mt76: mt7915: set VTA bit in tx descriptor
Git-commit: f9372753648ee1dd53de20e8d508a1569ea5b4d9
Patch-mainline: v5.16-rc1
References: bsc#1209980
The VTA (Valid for Txd Arrival time) bit should be set in tx descriptor,
which is necessary for WM fw to schedule SPL (station priority list)
normally before generating txcmd.
If it's not set, some unexpected wcids may be involved in SPL.
