[RFC V2 PATCH 0/4] Multiqueue support for tap and virtio-net/vhost
...le file descriptors to a signle netdev by:
qemu -netdev tap,id=hn0,fd=10,fd=11,...
Patch 2 introduce generic helpers in tap to attach or detach a file descriptor
from a tap device, emulated nics could use this helper to enable/disable queues.
Patch 3 modifies the NICState to allow multiple VLANClientState to be stored in
it, with this patch, qemu has basic support of multiple capable tap backend.
Patch 4 converts virtio-net/vhost to be multiple capable. The vhost device were
created per tx/rx queue pairs as usual.

- rebase to the latest
