The virtio spec already supports the virtio queue reset function. This patch set
is to add this function to the kernel. The relevant virtio spec information is
here:
https://github.com/oasis-tcs/virtio-spec/issues/124
virtio-net's queue disable/enable function based on virtio queue reset is here
https://github.com/fengidri/linux/commit/021165b4eda44f87c4b7771ef637bab2512d066f
I plan to include this patch in the subsequent virtio-net support AF_XDP
patch set.
Also regarding MMIO support for queue reset, I plan to support it after this
patch is passed.
Please review. Thanks.
