8.4. Test Network Loopback using fpgadiag

The test requires use of an external traffic generator to send traffic through QSFP ports, the --side host enables loopback on the host side of the Intel® Arria® 10 FPGA.
$	sudo fpgadiag -B 0x3e -m fpgalpbk --side host –-direction remote –-enable
To disable:
$	sudo fpgadiag -B 0x3e -m fpgalpbk --side host –-direction remote --disable
Note: Since all four Ethernet channels in the 4x25G configuration are in QSFP A, only one QSFP port indicates linkup status through LEDs.
