No. The code calling lisp_dev_xmit for example is actually calling ndo_start_xmit() function from struct net_device_ops, which is a pointer to a tunnel specific implementation. So if you want to modify LISP tunneling specifically, you should modify lisp_dev_xmit itself, or other code in lisp.c accordingly.
