8.3.15. MII Port Diagnostic Loopback
The RTL8309SB provides a MAC loopback function on the MII port to detect cable problems or far end existence. When this
function is enabled, the RTL8309SB will forward local and broadcast packets from the input of the MII port to the output of
the MII port, and drop unicast packets from the input of the MII port. The other port can still forward broadcast or unicast
packets to the MII port. This is especially useful for router application mass production tests.
