Subject: [PATCH] wifi: mt76: mt7996: fill txd by host driver
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 3b522cadedfe6e9e0e8193d7d4ab5aa8d0c73209

[ Upstream commit 3b522cadedfe6e9e0e8193d7d4ab5aa8d0c73209 ]

The hardware SDO has issue to fill txd for the moment, so fallback to
driver filling method.
