Subject: [PATCH 2/4] net/virtio: use iterator to destroy Virtio-user queues
Date: Wed, 27 Mar 2024 10:40:30 +0100	[thread overview]
Message-ID: <20240327094032.2400951-3-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20240327094032.2400951-1-maxime.coquelin@redhat.com>

This patch uses the freshly renamed iterator to destroy
queues at stop time. Doing this, we fix the missing
control queue destroy.

Fixes: 90966e8e5b67 ("net/virtio-user: send shadow virtqueue info to the backend")
Cc: stable@dpdk.org
