184 	 * - TOTAL_PORT_SHUTDOWN_ENA may be enabled only before OS loads

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
