4.4.1.4. Assert the i_tx_error to Invalidate a Packet

Assert i_tx_error to invalidate a packet that has already started to be transmitted on the i_tx_data bus. Since the IP core uses a cut-through mode, this is the only way to error the packet so that the link partner can detect it and handle appropriately.

Refer to the diagram below for an example of how to invalidate a packet in transition. Assert i_tx_error and i_tx_endofPacket for 1 clock cycle.
