Message-ID: <1398170586-6668-1-git-send-email-chenweilong@huawei.com> Date: Tue, 22 Apr 2014 20:43:06 +0800 From: Chen Weilong <chenweilong@...wei.com> To: <kaber@...sh.net>, <davem@...emloft.net> CC: <netdev@...r.kernel.org> Subject: [patch net-next] vlan: Don't allow vlan devices to change network namespaces. From: Weilong Chen <chenweilong@...wei.com> Like bonding, vlan as netdevice doesn't cross netns boundaries. Vlan port and vlan itself live in same netns.
