From 7976b1e9e3bfdd7ed1cfb21afc4a195655017f13 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Wed, 6 Feb 2019 13:17:17 +0200 Subject: mac80211: ignore quiet mode in probe Some buggy APs keep the CSA IE in probes after the channel switch was completed and can silence us for no good reason. Apply quiet mode only from beacons. If there is real channel switch going on, we will see the beacon anyway.
