Answer 1

在配置文件里把相关的DEBUG开关置为y，看看错误的具体信息。有可能是配置的某个特性网卡不支持导致的

谢谢，我刚刚找到了答案，这是DPDK的问题，后面的版本已经修复了。

net/i40e: fix sync phy type by adding retry
Some phy's take longer than others to come up. Add a retry to give
more phy's a chance to come up before returning an error.

Fixes: 2209c3e2c275 ("net/i40e: avoid PCI probing failure when using bogus SFP")

所以请问怎么解决？新手表示看不懂，这版本不能用？还是修改配置？
