This is to demonstrate the Cute-WR-DP that works in chain mode which
contains a WRS and three Cute-WR-DP nodes.
The WR switch acts as the Grandmaster(Layer 1) in this small network,
and three Cute-WR-DP boards are connected one by one. They are in Layer
2/3/4 of this network seperately.
In each board, use the blue SFP (AXGE-1254-0531) in SFP0 and red SFP
(AXGE-3454-0531) in SFP1. (The label of each SFP is on the PCB)
Use the command below to change the parameters of each port.
The SFP_PN is AXGE-1254-0531 or AXGE-3454-0531 if you use the SFPs
produced by AXCEN.
The units of dtx_value and drx_value are picosecond.
alpha value is depended on your fiber.
The port is 0 or 1. If without port, default value will be 0.
