I'm sorry I didn't reply in time.
I found the root cause.
In the pbuf. c file,add lwip/netif.h.such as:
#include "lwip/netif.h"

function signature might be miss typed in lwip/netif.h

void (l2_buffer_free_notify)(void *user_buf)
===>
void (l2_buffer_free_notify)(struct netif *netif,void *user_buf)

this function might be related to pppos and ip forward functional in NAPT function
