The EVB (virtual bridge) functionality should be disabled on older BE3 and Lancer chips if SR-IOV is disabled in the NIC's BIOS. This setting is identified by the zero value of total VFs reported by the card. The GET_HSW_CONFIG command cannot be used as it is not supported by these older chipset's FW.
