Public bug reported:
Currently, there are only 2 options True/False for port attribute
'admin_state_up', underneath they are mapped to 'ip link set <dev>
enable/disable'. However, in case of SR-IOV VF port the state can be set
to 'auto', which means the VF link state can follow that of PF. When PF
link goes down, VF link state will go down as well. And this
functionality is useful when the VMs use the link state as a trigger of
its own HA mechanism.
Therefore the expected change is to add a 3rd option admin_state_up
'auto' for neutron SR-IOV VF port.
