i225-IT under Linux with igc driver: kernel message "(unnamed net_device) (uninitialized): PHC"

[mmg]

Hi everyone,

we have developed a custom NIC board using the i225-IT Ethernet Controller and so far it works fine under Linux with the igc driver.

However, in the kernel log (via dmesg) we stumbled across this line regarding the i225:

igc 0000:0d:00.0 (unnamed net_device) (uninitialized): PHC

Can you help us determine what this means?
Is this an error, or what does it mean?

Thank you in advance and kind regards,
Marcel

Hello @mmg ,

Thank you for contacting Intel Embedded Community.

This message you are referring to comes from the open source driver which is supported by each Linux distributor (not by Intel); I suggest you contact your Linux distributor community support. As an example see this thread from Gentoo forum:
