Network namespace ported to 2.6.21-mm2

Hi all,

The network namespace patchset has been ported to 2.6.21-mm2.

They are still some issues but we are on it, for this reason the 
patchset is named netns1-beta1.

The patchset can be found here :

http://lxc.sourceforge.net/patches/2.6.21/2.6.21-mm2-netns1-beta1/

Documentation can be found here :

http://lxc.sourceforge.net/network.php

Any suggestions or comments are welcome.

Thanks.
