The limitation to only 1500 byte mtu's limits the utility of the veth device for testing routing. So implement implement a configurable MTU. For consistency I drop packets on the receive side when they are larger than the MTU. I count those drops. And I allow a little padding for vlan headers. I also test the mtu when a new device is created with netlink because that path currently bypasses the current mtu setting code.
