mac80211: allow driver to handle packet-loss mechanism
Based on consecutive msdu failures, mac80211 triggers CQM packet-loss
mechanism. Drivers like ath10k that have its own connection monitoring
algorithm, offloaded to firmware for triggering station kickout. In case
of station kickout, driver will report low ack status by mac80211 API
(ieee80211_report_low_ack).
This flag will enable the driver to completely rely on firmware events
for station kickout and bypass mac80211 packet loss mechanism.
