If the operator changes the media settings, then the NIC driver will call ether_mediachange() -> mii_mediachg() -> (for each PHY) phy_service(,, MII_MEDIACHG). A PHY service routine will reset and isolate its PHY if it is no longer selected. If the PHY is selected, then the service routine will either program the media type (e.g., IFM_ETHER|IFM_100_TX), or begin auto-negotiation (IFM_AUTO).
