Subject: [PATCH] mac80211: fix regression in sta connection monitor
Date: Mon, 21 Sep 2020 17:45:45 +0200	[thread overview]
Message-ID: <20200921154545.91971-1-nbd@nbd.name> (raw)

When the nulldata frame was acked, the probe send count needs to be reset,
otherwise it will keep increasing until the connection is considered dead,
even though it fine.

Fixes: 9abf4e49830d ("mac80211: optimize station connection monitor")
