使用4.4内核可以ping通局域网内主机和外网,

使用4.19内核可以ping通自己以及127.0.0.1,ping其他主机、网关和外网都返回Destination Host Unreachable

root@localhost:~# ethtool fm1-mac3

链接也都正常,可以排除硬件问题

root@localhost:~# arp -a
? (10.5.0.237) at <incomplete> on fm1-mac3

无法正确识别mac,手动设置mac后也无法ping通

是否是内核驱动问题?该如何排查、解决?

Please try 4.19 Linux Kernel and dtb files provided in LSDK 2004 release, I have uploaded them in the following link.

If your problem remains, please provide Linux Kernel booting up console log.
