So I don't think it's good idea to make rl(4) serve 8139C+.

perhaps, but re(4) doesn't work at the moment on this chipset, and i'd
rather have something which works, albeit a little poorly, than something
which doesn't.


Ok.

Yes. What `ident /boot/kernel/if_re.ko` shows?

$FreeBSD: src/sys/dev/re/if_re.c,v 1.46.2.19 2006/08/07 02:38:07 yongari

and the latest if_rlreg.c which i pulled down shows,

$FreeBSD: src/sys/pci/if_rlreg.h,v 1.51.2.7 2006/08/01 17:36:50 wpaul Exp $

i'm not using the loadable modules though, and am building the re(4) device
into the kernel directly.

the symptoms remain the same, i.e. IP traffic doesn't flow at all, though
'arp -an' does show the ethernet address of the other box attempting to
ping this.


Ok, this is important thing. It means Rx part works as expected.
Can you see tcpdump output on Tx side while ping command is in
progress?

the OP at
http://lists.freebsd.org/pipermail/freebsd-stable/2006-August/027356.html
mentioned that it was working fine before breakage was introduced
relatively recently (~ 2 weeks ago), and thus something's changed in the
interim which is causing this to happen.
