1.2.5.2.24 TCPIP_MAC_LinkCheck Function

bool TCPIP_MAC_LinkCheck(
    DRV_HANDLE hMac
);

This is a function that returns the current status of the link.

The TCPIP_MAC_Initialize() function should have been called. TCPIP_MAC_Open() should have been called to obtain a valid handle.

• True - If the link is up.

• False - If the link is down.

The stack will call this function periodically. Therefore this function is not required to initiate a new PHY transaction and to wait for the result. It can just initiate a new PHY transaction and return immediately the result of the previous transaction.
