180 * - LINK_DOWN_ON_CLOSE_ENA is configurable at host OS run-time and
181 * is supported by whole family of 7xx Intel Ethernet Controllers
182 * - TOTAL_PORT_SHUTDOWN_ENA may be enabled only before OS loads
183 * (in BIOS) only if motherboard's BIOS and NIC's FW has support of it
184 * - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought
185 * down by sending phy_type=0 to NIC's FW
186 * - when TOTAL_PORT_SHUTDOWN_ENA is used, phy_type is not altered,
