On my side, I have no plans to add what you need, so patches are very
welcome. I can help providing indications on how to get things done if
you have time to work on this. So I would suggest you fire at one
front at a time.

I would start by adding the assymmetric tunnel ID allocation that you
need, which should not be too complicated to add. You have to extend
the netlink interface that we have on gtp to support this.

I have just created a gtp specific kernel tree here:

http://git.kernel.org/cgit/linux/kernel/git/pablo/gtp.git/

more specifically, the GTP driver is at driver/net/gtp.c

You can submit patches based on that tree anytime. Please, read this
carefully:

https://www.kernel.org/doc/Documentation/SubmittingPatches

As I'll be taking your patches and submitting them to the Linux
networking kernel mailing list, I need that you make it in the right
way to reduce my maintainance burden here.

Thanks!
