Re: igc NIC not detected

Hi,

The I225 adapter family should be mostly supported by igc(4); it's hard to
say in your case because it looks like the NVM is invalid so the driver
won't do anything with the hardware. You may need a BIOS update that has a
valid NVM in it (or maybe redo it since it might not have happened
correctly), or there could be some other hardware issue that requires an
RMA.
