Subject: [PATCH v3 11/13] net/ionic: optimize device close operation
Date: Tue, 6 Feb 2024 19:13:15 -0800	[thread overview]
Message-ID: <20240207031317.32293-12-andrew.boyer@amd.com> (raw)
In-Reply-To: <20240207031317.32293-1-andrew.boyer@amd.com>

Use a single device reset command to speed up dev_close(). The LIF stop
and port reset commands are not needed.
This reduces the outage window when restarting the process by about 2ms
plus another 1ms per queue.
