Subject: vxlan: Fixed checksum caclculation offset

VXLAN uses csum_offload for IPv6 packets.

But without gso node we have csum calculated only for inner
packet.
This patch adds support for outer header csum calculation.
Checksum for inner packet should be calculated before
interface-output node (for example in vxlan node).

Type: fix
