ip4_forward return? (IDFGH-9883)

esp-lwip/src/core/ipv4/ip4.c

Line 661 in d5e56d0

ip4_forward(p, (struct ip_hdr *)p->payload, inp);

If ip_forward successfully forwards the pbuf, then why not consider going straight back without the need for further steps? I am confused, please enlighten!

[david-cermak]

after calling the ip4_forward() (no matter if successfully or not) we are going straight back, are we not?

esp-lwip/src/core/ipv4/ip4.c

Lines 669 to 670 in d5e56d0

	pbuf_free(p);
	return ERR_OK;

which further steps you mean? The latter call of pbuf_free() or checking/adding an error code to the function?

You are right, I see. I missed close brace here, thanks for explanation!
