failure of port create,which needs to update before

[Taoyunxiang]

Before creating a port, which needs to update the port information. In this case, an error is reported,like as the pic tells.

the cmd of neutron is "neutron port-create net-id"

when troubleshooting with logs,i find the code logic is to update before create,just as fellows.

            if port.get('fixed_ips') and sg_ids:
                addresses = ovn_acl.acl_port_ips(port)
                # NOTE(rtheis): Fail port creation if the address set doesn't
                # exist. This prevents ports from being created on any security
                # groups out-of-sync between neutron and OVN.
                for sg_id in sg_ids:
                    for ip_version in addresses:
                        if addresses[ip_version]:
                            txn.add(self._nb_idl.update_address_set(
                                name=utils.ovn_addrset_name(sg_id,
                                                            ip_version),
                                addrs_add=addresses[ip_version],
                                addrs_remove=None,
                                if_exists=False))

the path of code is /usr/lib/python2.7/site-packages/networking_ovn/common/ovn_clinet.py

when i change the value of 'if_exists' to True , all will fine .
