I looked deeper into this and try to move the list from global
resource to net struct and use per netns init... it's just a very big
task and I try to do my best there...
Also I figured out that the bridge code use a lot of global resources
which should also be per netns as well and I am worried that you can
actually move bridges to different namespaces. :-/

Just a status update - when I have time I try to do that... just need
time and it's not simple to do this change in llc.
