Request IP L4 traffic punt to the local TCP/IP stack.

Note

• UDP is the only protocol supported in the current implementation

Parameters

vm	vlib_main_t corresponding to the current thread
af	IP address family.
protocol	8-bits L4 protocol value UDP is 17 TCP is 1
port	16-bits L4 (TCP/IP) port number when applicable (UDP only)

Returns

0 on success, non-zero value otherwise
