Subject: [PATCH AUTOSEL 5.16 105/217] iwlwifi: mvm: avoid clearing a just saved session protection id
Date: Mon, 17 Jan 2022 21:17:48 -0500 [thread overview]
Message-ID: <20220118021940.1942199-105-sashal@kernel.org> (raw)
In-Reply-To: <20220118021940.1942199-1-sashal@kernel.org>
From: Shaul Triebitz <shaul.triebitz@intel.com>
[ Upstream commit 8e967c137df3b236d2075f9538cb888129425d1a ]
When scheduling a session protection the id is saved but
then it may be cleared when calling iwl_mvm_te_clear_data
(if a previous session protection is currently active).
Fix it by saving the id after calling iwl_mvm_te_clear_data.
