Hi all,

I'm not exactly sure on the format I'm supposed to submit patches in, so
I'll just follow what everybody else is doing.

Patch from Jason (jstubbs@work-at.co.jp):
This patch virtualizes the ipt_REDIRECT iptables module.

Missed two defines when bringing the patch forward from 2.6.8.
How embarrassing...

Jason,

I fixed error path in do_ve_iptables().
Here is the patch which is commited in 2.6.8.
It will be also commited in coming 2.6.16.

Thanks,
Kirill
