Re: [PATCH pom-ng] H.225 parser for h323-conntrack-nat

[Wang Jian <lark@linux.net.cn>]

Hi Max Kellermann,

It is very good news for me.

Please read back to my mail titled as "Need help on 2.6.11 and pom-ng
HEAD"

I want to make it works under 2.6.11 or 2.6.12. I really need your help
to finish it in time.

I will spend a day (ideally) to look into the new conntrack
infrastructure, and then I will spend time on every conntrack involved.
If the old code works, I think it is not very hard to port them to new
infrastructure. provided that new infrastruture is stable and good.
