status of ipchains in 2.6?

[David Mosberger <davidm@napali.hpl.hp.com>]

I recently discovered that ipchains is rather broken.  I noticed the
problem on ia64, but suspect that it's likely to affect all 64-bit
platforms (if not 32-bit platforms).  A more detailed description of
the problem I'm seeing is here:

Unlike ipchains, iptables works perfectly fine, so perhaps we just
need to update Kconfig to discourage ipchains on ia64 (and/or other
64-bit platforms)?
