Subject: [PATCH 10/15] mac80211: allow CSA to self with immediate quiet
Date: Wed, 6 Feb 2019 13:17:16 +0200 [thread overview]
Message-ID: <20190206111721.29283-11-luca@coelho.fi> (raw)
In-Reply-To: <20190206111721.29283-1-luca@coelho.fi>
From: Sara Sharon <sara.sharon@intel.com>
Currently, due to some buggy APs that continue to include
CSA IEs after the switch, we ignore CSA to same channel.
However, some other APs may do CSA to self in order to have
immediate quiet. Allow it. Do it only for beacons.
