Subject: [PATCH] net/nfp: fix representor port release queue problem
Date: Tue, 19 Mar 2024 15:07:54 +0800	[thread overview]
Message-ID: <20240319070754.398799-1-chaoyong.he@corigine.com> (raw)

From: Long Wu <long.wu@corigine.com>

The PF representor port's queue is different from the VF/physical
representor port. So the release process in close port should
be different too.

Fixes: 39b3951 ("net/nfp: fix resource leak for exit of flower firmware")
