Re: kern/59876 (igc0: unable to initialize)

[Shinichi Doyashiki <clare%csel.org@localhost>]

the ASROCK J4125M (BIOS version 1.60) requires PCI fixup kernel options for the 
Intel i226-V.  the igc driver in the NetBSD 11_RC6 GENERIC kernel cannot 
initialize the Intel i226-V add-on card on the ASROCK J4125M
mainboard.

with kernel with PCI BUS/ADDR/INTR FIXUP options:
