another question on vDPA vs vendor specific driver portion...
Are the subsystem vendor & device IDs to be different from the primary (Red
Hat) versions as there has to be a way for a vendor specific driver to

Does this mean that SW takes over the datapath during LM?
If so, is there any infrastructure to "gracefully" do a hand-off from HW
mode (pci device is managing the rings) to SW mode, in that when switching
from HW->SW, HW is stalled & quiesced, then the SW takes from where HW

Given that this new feature clarifies RSS, should the existing references
to RSS be updated in the spec to have RSS replaced with RFS (aka Receive

Can we add some words about the new fields in the virtio_net_hdr
structure, such as SHOULD, MUST,...
Also, should the virtio_net_hdr be bumped to v2?

batchmode for tx at least in packed rings.
Finally, i would suggest a means to
