Support VIRTIO_F_RING_RESET for virtio-net and vhost-user in virtio pci

[PATCH 01/16] virtio-pci: virtio_pci_common_cfg add queue_notify_data

Posted by Kangjie Xu 3 years, 6 months ago

From: Xuan Zhuo <xuanzhuo@linux.alibaba.com>

Add queue_notify_data in struct virtio_pci_common_cfg, which comes from
here https://github.com/oasis-tcs/virtio-spec/issues/89

Since I want to add queue_reset after queue_notify_data, I submitted
this patch first.

This should be done by script/update-linux-headers.sh.

Thanks
