This netdev op allows the PF driver to control the virtual link state of the VF devices. This can be used to deny naughty VF drivers access to the wire, or to allow VFs (regardless of temperament) to communicate with each other over the device's internal switch even though external link is down. Add the actual ndo function, and modify vc_notify_link_state to check the link status of each VF before sending a message in the case when physical link changes state.
