fastpath_local_hook() function apparently does nothing.
It was created to demo the use of the hook functionality.
Some comment above the function to explain why is it here would be nice.

/** local hook
*

• @param pkt odp_packet_t
• @param protocol int
• @return int

*/
static enum ofp_return_code fastpath_local_hook(odp_packet_t pkt, void *arg)
{
int protocol = *(int *)arg;
(void) pkt;
(void) protocol;
return OFP_PKT_CONTINUE;
}
