Bug Description

VXLAN + Linux Bridge is too slow because
VXLAN outer header check sum is zero and gro is not work
on the reciever. This make VXLAN slow.
Adding udp checksum in outer header resolve this problem.

Open vSwitch agent already resolved by #1492111.

Linux Bridge should support outer udp checksum.

I'm looking at https://bugs.launchpad.net/neutron/+bug/1492111 which looks awfully similar, just for OVS and not LB. Is this a case of the patch set that was released for that bug not addressing LB correctly?
