From: Ying Xue Date: Fri, 18 Oct 2013 05:23:19 +0000 (+0200) Subject: tipc: correct return value of recv_msg routine X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=679815834857d5305dae108a03addccf16d86868;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git tipc: correct return value of recv_msg routine Currently, rcv_msg() always returns zero on a packet delivery upcall from net_device. To make its behavior more compliant with the way this API should be used, we change this to let it return NET_RX_SUCCESS (which is zero anyway) when it is able to handle the packet, and NET_RX_DROP otherwise. The latter does not imply any functional change, it only enables the driver to keep more accurate statistics about the fate of delivered packets.
