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

[Kangjie Xu]

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.
