port number和lane是有关系的。具体请看手册table 3-107
The lowest numbered lane of the path used in a port is the port number as follows:
• Lane A: port 0
• Lane B: port 1
• Lane C: port 2
• Lane D: port 3
For example, in the 2x+1x+1x configuration, the 2x port uses lanes A and B and is numbered port 0; the 1x ports use C and D respectively and so are numbered 2 and 3 www.ti.com.cn/.../sprugw1c.pdf
也可研究一下srio_identify_used_ports_lanes函数的配置。
如果是 Mode 4: One independent 4x port in lanes {A,B,C,D}*/，修改为port0使能试一下。
