veth: move loopback logic to common location
The veth driver contains code to forward an skb
from the start_xmit function of one network
device into the receive path of another device.
Moving that code into a common location lets us
reuse the code for direct forwarding of data
between macvlan ports, and possibly in other
drivers.
