By default VFs are not trusted. Add ndo_set_vf_trust support to toggle a new per-VF bit. Coupled with FW with this capability allows a trusted VF to change its MAC even after being administratively set by the PF. Also populate the trusted field on ndo_get_vf_config. Add the same ndo to the representors. Signed-off-by: Pablo Cascón <pablo.cascon@netronome.com> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.
