Subject: [PATCH v9 20/32] virtio: queue_reset: add VIRTIO_F_RING_RESET
Date: Wed, 6 Apr 2022 11:43:34 +0800 [thread overview]
Message-ID: <20220406034346.74409-21-xuanzhuo@linux.alibaba.com> (raw)
In-Reply-To: <20220406034346.74409-1-xuanzhuo@linux.alibaba.com>
Added VIRTIO_F_RING_RESET, it came from here
https://github.com/oasis-tcs/virtio-spec/issues/124
This feature indicates that the driver can reset a queue individually.
