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