I admit, I missed this one... But I'll improve, since, according to my
expectations, my mind "blacklisted" possibility that GbE descriptor is
corrupted. I am more on Linux/kernel side, and every day I read somebody's
dmesg, which come out of/based upon completely healthy BIOS. Coreboot as
BSP asset for ASUS, GIGABYTE and such vendors, in mobile, WS, DT and
Servers is not almost at all present?! :-(

Anyway, good catch, I'll add this one to my (growing) rich understanding of
dmesg logs! :-)

Thank you,
Zoran
