When the IXF1104 is configured in this loopback mode, all of the MAC functions and features are available, including flow control and pause-packet generation.

To configure the IXF1104 to use the line-side loopback mode, the “Loop RX Data to TX FIFO (Line-Side Loopback) Ports 0 - 3 ($0x61F)" must be configured. Each IXF1104 port has a unique bit in this register designated to control the loopback. It is possible to have individual ports in a loopback mode while other ports continue to operate in a normal mode.

Note: Line side interface loopback packets also appear at the SPI3 interface.
