Subject: [PATCH] net/ice: check process type in reset operation
Date: Mon, 26 Sep 2022 13:44:05 +0000	[thread overview]
Message-ID: <20220926134405.304919-1-qiming.yang@intel.com> (raw)

The secondary processes are not allowed to release shared resources.
so the stop and reset operation are forbidden in a secondary process.
