From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gao feng Subject: [PATCH] veth: allow to setup multicast address for veth device Date: Fri, 4 Oct 2013 16:52:24 +0800 Message-ID: <1380876744-606-1-git-send-email-gaofeng@cn.fujitsu.com> Cc: pablo@netfilter.org, davem@davemloft.net, edumazet@google.com, kaber@trash.net, hannes@stressinduktion.org, Gao feng To: netdev@vger.kernel.org Return-path: Received: from cn.fujitsu.com ([222.73.24.84]:2324 "EHLO song.cn.fujitsu.com" rhost-flags-OK-FAIL-OK-OK) by vger.kernel.org with ESMTP id S1752431Ab3JDIvR (ORCPT ); Fri, 4 Oct 2013 04:51:17 -0400 Sender: netdev-owner@vger.kernel.org List-ID: 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.
