LISP-GPE decap dispatcher.

Node Identifier:
lisp_gpe_input_inline

LISP-GPE decap dispatcher.

Decaps IP-UDP-LISP-GPE header and based on the next protocol and in the GPE header and the vni decides the next node to forward the packet to.

Parameters
[in]vmvlib_main_t corresponding to current thread.
[in]nodevlib_node_runtime_t data for this node.
[in]framevlib_frame_t whose contents should be dispatched.
Returns
number of vectors in frame.
