================================================================================
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
Also regarding MMIO support for queue reset, I plan to support it after this
patch is passed.
#14-#17 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.
