Re: EG20T and Micrel KSZ9021 Gigabit Ethernet

James Kosin [off-list ref] :

I'm tempted to reconfigure to remove that; but, am afraid that there is
no other driver for the network.  The only other set of drivers that
seem to be related are for the intel directory; but, these seem to be
intel specific.  I don't see support for this combination.

Anyone have an idea where I need to start?

drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe_main.c
[...]
        pr_info("EG20T PCH Gigabit Ethernet Driver - version %s\n",DRV_VERSION);

It would seem a sensible candidate driver for your chipset (EG20T) built-in MAC.

Why do you want to use something else ?
