[Devel] [PATCH 09/14] venet: prevent to change network namespaces

[Kirill Tkhai]

Porting patch diff-venet-prevent-to-change-network-namespaces from 2.6.32:

venet is a local device.

Without this patch it may be moved in CT0:
vzctl exec 101 ip link set name xxx dev venet0
vzctl set 101 --netdev_del xxx --save
