From 5c70ef85a2f26d8a0e1aaa7b4cbfff44fda36585 Mon Sep 17 00:00:00 2001 From: Gao feng Date: Fri, 4 Oct 2013 16:52:24 +0800 Subject: [PATCH] veth: allow to setup multicast address for veth device We can only setup multicast address for network device when net_device_ops->ndo_set_rx_mode is not null. Some configurations need to add multicast address for net device, such as netfilter cluster match module. Add a fake ndo_set_rx_mode function to allow this operation.
