Please note that there are three different PDP contexts for IP:
* IPv4 only (what gtp.c implements so far)
* IPv6 only
* dual IPv4+IPv6 (called IPv46)
This information will have to be provisioned by the control plane
via netlink for each PDP context. The kernel module then needs to
make sure that on a v4-only context no IPv6 packets are accepted
and vice-versa.
Your proposed patch is missing this kind of screening function and
I would imagine it could introduce all kinds of security problems :/
