From 99301ba11cb72f68f4e43e5778106035bd6965c4 Mon Sep 17 00:00:00 2001 From: Weilong Chen Date: Thu, 23 Jan 2014 11:07:22 +0800 Subject: [PATCH] team: Don't allow team devices to change network namespaces. Like bonding, team as netdevice doesn't cross netns boundaries. Team ports and team itself live in same netns. Signed-off-by: Weilong Chen Signed-off-by: David S.
