bnx2x: VF can report link speed
Until now VFs were oblvious to the actual configured link parameters.
This patch does 2 things:
1. It enables a PF to inform its VF using the bulletin board of the link
configured, and allows the VF to present that information.
2. It adds support of `ndo_set_vf_link_state', allowing the hypervisor
to set the VF link state.
