From 7c77ab24e30bad7598b5cfda93be6f32ed439c2f Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Sun, 9 Dec 2012 20:48:13 +0000 Subject: [PATCH] net: Allow DCBnl to use other namespaces besides init_net Allow DCB and net namespace to work together. This is useful if you have containers that are bound to 'phys' interfaces that want to also manage their DCB attributes. The net namespace is taken from sock_net(skb->sk) of the netlink skb.
