From 119bebff244b139cf63ab70809e3a2d357de13b2 Mon Sep 17 00:00:00 2001 From: Yi-Chia Hsieh Date: Thu, 21 Sep 2023 14:04:02 -0700 Subject: [PATCH] wifi: mt76: mt7996: enable PPDU-TxS to host Enable PPDU TxS by default. This makes the driver able to get Tx rate information from TxS. The driver will also refresh BA session timer on receive of PPDU TxS when WED is on.
