>   link state.
> - bringing up/down the VF will cause the link state update of VF port
>   netdev.
> - enable/disable VF link state via ndo_set_vf_link_state will update the
>   admin state of associated VF port netdev.
> - bringing up/down the PF port netdev updates the link state of PF based on
>   the hw link info.
> - bringing up/down the PF will update the link state of PF port netdev.
