From f91c58d68b8638530e0eb2fec76c5b9e429ca39a Mon Sep 17 00:00:00 2001 From: Zhang Shengju Date: Wed, 7 Dec 2016 14:52:53 +0800 Subject: [PATCH] icmp: correct return value of icmp_rcv() Currently, icmp_rcv() always return zero on a packet delivery upcall. To make its behavior more compliant with the way this API should be used, this patch changes this to let it return NET_RX_SUCCESS when the packet is proper handled, and NET_RX_DROP otherwise.
