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 Also regarding MMIO support for queue reset, I plan to support it after this patch is passed. #9-#12 is the disable/enable function of rx/tx pair implemented by virtio-net using the new helper. This function is not currently referenced by other functions. It is more to show the usage of the new helper, I not sure if they are going to be merged together. Please review. Thanks.
