Hi Ti,
We are looking into an issue that Ethernet sometimes cannot work well.
We are using Linux SDK 7 RT version, we know it' quite old version.
We have two ethernet ports on our customized board.
When this issue happened, we found only port 1 cannot work well and port 2 always working good.
We tried to use ethtool to get some info as below, and we got rx_good_frames: 0.
Could you let us know what is rx_good_frames meaning?
