Hi All, This patchset presents one of the possible level 2 network namespace implementation. The most of the code is done by Andrey Savochkin and already published here. I've ported his code over Cedric's patchset and latest -mm tree. The last patch in this patchset introduces two kinds of network namespaces - level 2 and level 3. P.S. Performance testing results will be later, I need some time for this. -- Thanks, Dmitry.
