Comment 2 for bug 1450420

The only thing needed is to accept endpoints / interfaces of the form ibx.80yz . currently l23network fails for these interfaces since it tries to verify 80yz is a valid vlan, and there isn't any other way to define non Ethernet interfaces...

I discussed about it with Sergey Vasilenko and in Mellanox plugin we currently have a workaround that uses l23_stored_config and then executing ifdown ifup.
