From 6724b0a9a748fde88fc6bbe3d4ab183f6acd6f26 Mon Sep 17 00:00:00 2001 From: Shayne Chen Date: Mon, 18 Oct 2021 16:07:05 +0800 Subject: [PATCH] mt76: mt7915: set VTA bit in tx descriptor 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.
