Re: fec_nic_drv no packet ever send on imx8mm

Hello Jean-Adrien,

I have no device-specific hints, just some general tips/questions.

- Your board seems to use a different PHY from imx8q_evk. Is this correct?

- The driver logs the link is up in full-duplex 1Gbps. Does your switch confirm this with its LED state?

- I spotted some messages about fec_enet_rx_queue in the log. Does your driver receive any packets from the wire yet? If yes, is the content of the packets reasonable (you could just log some bytes into the packet while sending ARP requests from your host)?

- What happens if you unplug/plug the ethernet cable at runtime?

- Did you check that a minimal Linux with your configuration is able to drive the FEC?
