r200580 ipfw.ko kldload failure

[David Horn]

Luigi --

I am seeing a kldload failure for ipfw.ko after the latest -current commits
(fails for r200580 - r200633 inclusive) for ipfw:

link_elf_obj: symbol ipfw_dyn_attach undefined
linker_load_file: Unsupported file type

dhorn-1520# uname -a
FreeBSD dhorn-1520 9.0-CURRENT FreeBSD 9.0-CURRENT #4 r200623M: Thu Dec 17
01:42:13 EST 2009     root at dhorn-1520:/usr/obj/usr/src/sys/DHORN  amd64

The latest svn revision that kldload ipfw.ko works properly for me is
r200567.  (amd64 GENERIC + ahci + ATA_CAM in kernel config)

As well, in an attempt to test a separate fix for /etc/rc.firewall, I was
attempting to do this without INET6 in my kernel config, and ipfw failed to
load on r200567 with a different error:

link_elf_obj: symbol in6_cksum undefined
linker_load_file: Unsupported file type

I have not attempted to go back to revisions prior to r200567 yet.  Let me
know if you need me to narrow the no INET6 case down to a specific commit.

--Thanks!
