Subject: [PATCH AUTOSEL 5.4 113/130] iwlwifi: mvm: disconnect if channel switch delay is too long
Date: Tue, 22 Dec 2020 21:17:56 -0500	[thread overview]
Message-ID: <20201223021813.2791612-113-sashal@kernel.org> (raw)
In-Reply-To: <20201223021813.2791612-1-sashal@kernel.org>

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 87d9564e14cf5d05e4f1fa4eb7c55d798427f1dd ]

If the channel switch delay that we would incur after the channel
switch actually happens is longer than the quiet time we're willing
to tolerate, disconnect as well.
