NetPhy_LinkStateSet()
The Ethernet PHY’s LinkStateSet() function determines the current Ethernet link state. Results are passed back to the caller within a NET_DEV_LINK_ETHER structure which contains fields for link speed and duplex. This function is called periodically by µC/TCP-IP.

Note that since every PHY driver’s LinkStateSet() function is accessed only by function pointer via the PHY driver’s API structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.

Pointer to a link state structure with link state information to configure. The NET_DEV_LINK_ETHER structure contains two fields for link speed and duplex. Link speed is set via plink_state->Spd :
NET_PHY_SPD_10NET_PHY_SPD_100And link duplex is set via plink_state->Duplex :
NET_PHY_DUPLEX_HALFNET_PHY_DUPLEX_FULL...
