Open Stack

Hi Kuryr team,

I just notice, this can be fixed in kuryr bind code.
I submit a bug to track this:
https://bugs.launchpad.net/kuryr-libnetwork/+bug/1613528

And patch sets are here:
https://review.openstack.org/#/c/355712/
https://review.openstack.org/#/c/355714/

Thanks.

Regards,
Liping Mao
