XFITX/XFIRX与SFP+ 1888247-2&2007194-1直连
已将TX_DISABLE拉低使能传输，RATE_SELECT拉高
使用LC-LC多模光纤与INTEL(R) ETH CONVERGED NTWK ADPTR X520-SR2连接
故障现象：
INTEL(R)万兆以太网卡一直重复 连接-断开-连接-断开
请问是对xgbe接口配置有问题还是硬件设计有问题，该如何修改，谢谢
Shine：
把设备树里的xgbe_subsys, xgbe_pcsr, xgbe_serdes, and netcpx 这些节点的status设成ok试试。

回复 Shine:
谢谢，已将设备树里xgbe_subsys, xgbe_pcsr, xgbe_serdes, and netcpx 这些节点的status设成okay，故障一致
