 578 * with following differences:
 579 * - LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time and is
 580 *   supported by whole family of 7xx Intel Ethernet Controllers
 581 * - TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
 582 *   only if motherboard's BIOS and NIC's FW has support of it
 583 * - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought down
 584 *   by sending phy_type=0 to NIC's FW
 585 * - when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
 586 *   the link is being brought down by clearing bit (I40E_AQ_PHY_ENABLE_LINK)
