the reason behind handling the echo requests in the GGSN instead of

one?
because when you send an ECHO request, you want to know if the full GTP
stack on the other side is still alive, both for control and for user
plane? If you automatically replied to them from the kernel, it mihgt
be that just the user plane (kernel space) is still alive, while the
control plane (user space) is already dead?
