This change was initially aimed at a smaller scope: use self consistent
default for ovs lwt devices/tunnel terminations.
If there is agreement, I can post a separate patch changing the default
rx checksum setting for plain vxlan and geneve[1] devices tunneling over
ipv6.

[1] according to the ietf draft the geneve devices have the same
checksum requirement than vxlan ones
