This patch corresponds to a Linux kernel patch extending the kernel GTP
to also cover the SGSN role, not just the GGSN role. In order to keep
the API/behavior compatible, gtp_dev_create() will continue to create
GGSN-side tunnels, while a new gtp_dev_create_sgsn() is introduced to
create SGSN-side tunnels.

So we can fully test packet decapsulation without a full blown openggsn
setup by injecting packets and using this simple tool.
