[参考译文] DP83TC811-Q1：每个帧上的 RX 错误

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1443514/dp83tc811-q1-rx-errors-on-every-frame

工具与软件：

大家好、团队成员：

我遇到了 DP83TC811的 RX 问题。 ethtool 显示它是由 CRC 错误导致的。 测试设置为：

Mac <-> dp83tc811 <-> rddrunone t1适配器<->路由器

我将 dp83tc811配置为 RGMII 模式。 我检查了 SQI 寄存器、它指示链路状态良好。 我可以做些什么来进一步调试该问题？
