Subject: [PATCH v2 02/16] net/enetfec: fix restart issue
Date: Fri,  7 Oct 2022 08:57:29 +0530	[thread overview]
Message-ID: <20221007032743.2129353-3-g.singh@nxp.com> (raw)
In-Reply-To: <20221007032743.2129353-1-g.singh@nxp.com>

From: Apeksha Gupta <apeksha.gupta@nxp.com>

Queue reset is missing in restart because of which
IO cannot work on device restart.

This patch fixes the issue by resetting the queues on
device restart.

Fixes: b84fdd39638b ("net/enetfec: support UIO")
