Check for split horizon violations.
Return 0 if split horizon check passes, otherwise return non-zero. Packets should not be transmitted out an interface with the same split-horizon group as the input interface, except if the shg
is 0 in which case the check always passes.

Output node for interfaces/tunnels which was in L2 mode but were changed to L3 mode or possibly deleted thereafter.
(constructor) VLIB_REGISTER_NODE (l2output_bad_intf_node)
On changing forwarding mode of any tunnel/interface from L2 to L3, its entry in l2_output_main table next_nodes.output_node_index_vec[sw_if_index] MUST be set to the value of L2OUTPUT_NEXT_BAD_INTF. Thus, if there are stale entries in the L2FIB for this sw_if_index, l2-output will send packets for this sw_if_index to the l2-output-bad-intf node which just setup the proper drop reason before sending packets to the error-drop node to drop the packet. Then, stale L2FIB entries for delted tunnels won't cause possible packet or memory corrpution.
