linuxbridge agent delete a physcial interface

[mouadino]

How to reproduce ?
===============

1. Use Linux bridge agent.
2. Set the physical interface to something like:

  physical_interface_mappings= physnet1:eth0,physnet2:eth0.4000
3. Start using the physnet2 by creating a port for example ...

What happen ?
===========

As soon as no one is using the bridge anymore and that the bridge need to be deleted, eth0.4000 is also deleted.

What is Expected ?
===============

eth0.4000 to not be deleted, it's a physcial interface afterward, neutron didn't create it, neither he should delete it.

    Fix usage of netaddr '.broadcast'

    netaddr 0.7.16 changed the behavior of IPNetworks with /31 and /32
    prefixes to make their 'broadcast' attribute return None. This patch
    replaces the use of the attribute with a -1 index lookup to get the
    last address instead.

    Some Intel cards don't support setting link state, so to
    resolve it the SR-IOV mech driver supports agent and agent less mode.
    From Liberty the SR-IOV agent brings more functionality like

    (of course I already talked with Intel Guys to get their approval)
