From ed816f6ba8b5e3df609e5fc53f7bcb09bdaa16be Mon Sep 17 00:00:00 2001 From: David Bauer Date: Wed, 17 May 2023 12:04:00 +0200 Subject: [PATCH] mac80211: always use mac80211 loss detection ath10k does not report excessive loss in case of broken block-ack sessions. The loss is communicated to the host-os, but ath10k does not trigger a low-ack events by itself. The mac80211 framework for loss detection however detects this circumstance well in case of ath10k. So use it regardless of ath10k's own loss detection mechanism.
