Continuous Data Transmission from MAC Function

Description

When you switch the MAC function from half-duplex to full-duplex mode while it is transmitting data, the MAC function continuously sends data out through the MII even when you are not sending any data to the MAC function.

This issue affects variants of MAC with internal FIFO buffer operating in half-duplex mode.

Workaround/Fix

No workaround.This issue is fixed in version 11.0 of the Triple-Speed Ethernet MegaCore function.
