Determines the link status of the network interface.

Parameters
netif_descNetwork interface descriptor.
Returns
This function returns:
  • FNET_FALSE if the network link is disconnected.
  • FNET_TRUE if the network link is connected.

This function determines if the netif interface is marked as connected to a network or not. The Ethernet network interface gets this status from the PHY.
