552 /* TOTAL_PORT_SHUTDOWN
553 * Allows to physically disable the link on the NIC's port.
554 * If enabled, (after link down request from the OS)
555 * no link, traffic or led activity is possible on that port.
557 * If I40E_FLAG_TOTAL_PORT_SHUTDOWN_ENABLED is set, the
558 * I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to true
559 * and cannot be disabled by system admin at that time.
560 * The functionalities are exclusive in terms of configuration, but they also
561 * have similar behavior (allowing to disable physical link of the port),
562 * with following differences:
563 * - LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time and is
564 * supported by whole family of 7xx Intel Ethernet Controllers
565 * - TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
566 * only if motherboard's BIOS and NIC's FW has support of it
567 * - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought down
568 * by sending phy_type=0 to NIC's FW
569 * - when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
570 * the link is being brought down by clearing bit (I40E_AQ_PHY_ENABLE_LINK)
571 * in abilities field of i40e_aq_set_phy_config structure
