Subject: [PATCH] mt76: do not send BAR frame on tx aggregation flush stop
Git-commit: e3ca8fa0ca2423c7fcfc26cd5442bcd5373010bc
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
There is no need to send a BAR frame after stopping aggregation, and doing
so could lead to sending class 3 frames after deauthentication from an AP
