lwip compile error (IDFGH-1655)

[chegewara]

In menuconfig disabling this option:
LWIP->TCP->Queue incoming out-of-order segments (CONFIG_TCP_QUEUE_OOSEQ)
causes this error:

components/lwip/lwip/src/core/pbuf.c: In function 'pbuf_free':
components/lwip/lwip/src/core/pbuf.c:792:29: error: dereferencing pointer to incomplete type 'struct netif'
               && p->l2_owner->l2_buffer_free_notify != NULL) {

esp-idf version: v3.2

Similar situation on commit 6ccb4cf (HEAD, tag: v3.3)

Hi, I am facing the same error.
Is this issue has been fixed ?

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"

[kangg18]

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
