   4 Subject: [PATCH] mac80211: always use mac80211 loss detection
   5
   6 ath10k does not report excessive loss in case of broken block-ack
   7 sessions. The loss is communicated to the host-os, but ath10k does not
   8 trigger a low-ack events by itself.
   9
  10 The mac80211 framework for loss detection however detects this
  11 circumstance well in case of ath10k. So use it regardless of ath10k's
  12 own loss detection mechanism.
  13
  14 Patching this in mac80211 does allow this hack to be used with any
  15 flavor of ath10k/ath11k.
