The dev_forward_skb() assignment of pkt_type should be done
after the call to eth_type_trans().
ip-encapsulated packets can be handled by localhost. But skb->pkt_type
can be PACKET_OTHERHOST when packet comes via veth into ip tunnel device.
In that case, the packet is dropped by ip_rcv().
Although this example uses gretap. l2tp-eth also has same issue.
For l2tp-eth case, add dummy device for ip address and ip l2tp command.

Applied, but I had to adjust the patch because in net-next we use
a new helper function (skb_scrub_packet()) to clear things out from
dev_forward_skb().
What about calling skb_scrub_packet() after eth_type_trans()?
I wonder if the same problem may happen the day gre will support x-netns,
because skb_scrub_packet() is also called before eth_type_trans() in
ip_tunnel_rcv().
