567 /* TOTAL_PORT_SHUTDOWN
568 * Allows to physically disable the link on the NIC's port.
569 * If enabled, (after link down request from the OS)
570 * no link, traffic or led activity is possible on that port.
572 * If I40E_FLAG_TOTAL_PORT_SHUTDOWN_ENABLED is set, the
573 * I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to true
574 * and cannot be disabled by system admin at that time.
575 * The functionalities are exclusive in terms of configuration, but they also
576 * have similar behavior (allowing to disable physical link of the port),
577 * with following differences:
578 * - LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time and is
579 * supported by whole family of 7xx Intel Ethernet Controllers
580 * - TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
581 * only if motherboard's BIOS and NIC's FW has support of it
582 * - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought down
583 * by sending phy_type=0 to NIC's FW
584 * - when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
585 * the link is being brought down by clearing bit (I40E_AQ_PHY_ENABLE_LINK)
586 * in abilities field of i40e_aq_set_phy_config structure
