[RFC V2 PATCH] virtio-spec: ack the announce notification through ctrl_vq
During link announcement, driver needs a method to notify device that it has
received the notification and let it clear the VIRITO_NET_S_ANNOUNCE bit in the
status field. Doing this through a dedicated command looks suitable for all
platforms (especially for the ones who don't trap the status read or write) with
a ctrl vq and can solve the race between host and guest.
So this patch makes

[rfc] virtio-spec: introduce VIRTIO_NET_F_MULTIQUEUE
This patch introduces the multiqueue capabilities to virtio net devices. The
number of tx/rx queue pairs available in the device were exposed through config
space, and driver could negotiate the number of pairs it wish to use through
ctrl vq.

[PATCHv2] virtio-spec: virtio network device multiqueue support
At Jason's request, I am trying to help finalize the spec for
the new multiqueue feature.
Changes from Jason's rfc:
- reserved vq 3: this makes all rx vqs even and tx vqs odd, which
looks nicer to me.
- documented packet steering, added a generalized steering programming
command. Current modes are single queue and host driven multiqueue,
but I envision support for guest driven
