MFC virtio-net changes.
Re-tested with NetBSD/amd64 5.2.2, 6.1.4 and 7-beta.
r271299:
Add a callback to be notified about negotiated features.
r271338:
Allow vtnet operation without merged rx buffers.
NetBSD's virtio-net implementation doesn't negotiate
the merged rx-buffers feature. To support this, check
to see if the feature was negotiated, and then adjust
the operation of the receive path accordingly by using
a larger iovec, and a smaller rx header.
In addition, ignore writes to the (read-only) status byte.
