This commit adds the feature bit and associated mtu device entry for the
virtio network device. Future commits will make use of these bits to
support negotiated MTU.

why split it out? Pls squash with the next patch.

data structure changes, and then make a commit which hooks it up.  I'll
squash this in the future.
