 576 * - LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time and is

 578 * - TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
 579 *   only if motherboard's BIOS and NIC's FW has support of it
 580 * - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought down
 581 *   by sending phy_type=0 to NIC's FW
 582 * - when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
