FreeBSD pegasus.home.net 2.2.6-STABLE FreeBSD 2.2.6-STABLE #1: Tue May 26 14:46:22 MET DST 1998 ugo@pegasus.home.net:/usr/src/sys/compile/PEGASUS i386
>Description:
Subject says it all: I ported PnP support for NE2000 and compatibles back
from -current to -stable (a lot of cut&paste ;-)
Please note that I added a vendor ID that wasn't present in -current
sources (WSC9008), so you may think to commit that there too.
P.S.: I hope that i386 is the right category for this report: I was in
doubt between kern and i386...
>How-To-Repeat:
Insert a PnP NE2000 card into your -stable box.
