>Port representor is used to manage VF from host side. To allow it each created
>representor registers netdevice with random hw address. Also devlink port is
>created for all representors.
>
>Port representor name is created based on switch id or managed by devlink
>core if devlink port was registered with success.
>
>Open and stop ndo ops are implemented to allow managing the VF link state.
>Link state is tracked in VF struct.
>
>Struct ice_netdev_priv is extended by pointer to representor field. This is
>needed to get correct representor from netdev struct mostly used in ndo calls.
>
>Implement helper functions to check if given netdev is netdev of port
>representor (ice_is_port_repr_netdev) and to get representor from netdev
>(ice_netdev_to_repr).
>
>As driver mostly will create or destroy port representors on all VFs instead of
>on single one, write functions to add and remove representor for each VF.
>
>Representor struct contains pointer to source VSI, which is VSI configured on
>VF, backpointer to VF, backpointer to netdev, q_vector pointer and
>metadata_dst which will be used in data path.
