 181	 * link of the port), with following differences:
 182	 * - LINK_DOWN_ON_CLOSE_ENA is configurable at host OS run-time and
 183	 *   is supported by whole family of 7xx Intel Ethernet Controllers
 184	 * - TOTAL_PORT_SHUTDOWN_ENA may be enabled only before OS loads
 185	 *   (in BIOS) only if motherboard's BIOS and NIC's FW has support of it
 186	 * - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought
 187	 *   down by sending phy_type=0 to NIC's FW
 188	 * - when TOTAL_PORT_SHUTDOWN_ENA is used, phy_type is not altered,
 189	 *   instead the link is being brought down by clearing
 190	 *   bit (I40E_AQ_PHY_ENABLE_LINK) in abilities field of
