Code Issues Proposed changes

Skip ovsdb_monitor events for ports with ofport=-1

Browse Source 
There is no need to trigger neutron-openvswitch-agent to
start processing ports in case if invalid port (with
ofport=-1) will be added to bridge.
Such port will be processed later when ofport will be
changed.
