Subject: [PATCH] veth: allow to setup multicast address for veth device
Date: Fri, 4 Oct 2013 16:52:24 +0800 [thread overview]
Message-ID: <1380876744-606-1-git-send-email-gaofeng@cn.fujitsu.com> (raw)
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.
