agent works with only the first port IP if the port is configured with multiple IPs

[Vedamurthy Joshi]

Build 1.10 10

From neutron , we can have more than one IP for a port.
But in agent, we only see 1 IP associated with the port.

root@nodec22:~# neutron port-create test1 --fixed-ip ip_address=10.1.1.10 --fixed-ip ip_address=10.1.1.11

contrail doesn't support multiple IP on port. Will consider post 1.10

[Édouard Thuleau (ethuleau)]

So less or equal 1.10 releases need to raise an exception if user tries to create a port with more than one IP.
Does contrail support to have multiple subnets on one network and an IP per subnet?

Numan also opened a bug on the OpenContrail launchpad related to that one.
