Is this specific of MX8Menlo or something we should have on verdin-imx8mm instead? I am not aware of any report on this issue on the verdin, on the other hand the verdin imx8mm has normally only one ethernet interface, and this is the one from the verdin SOM. Francesco

This is specific to this particular carrier board and does not apply to Dahlia board or Verdin SoM.

The ethernet PHY on MX8Menlo board takes a while to come out of reset, increase the auto-negotiation timeout to prevent it from timing out in case the ethernet is used right after the board was reset.
