[NETNS]: struct net content re-work (v3)
Recently David Miller and Herbert Xu pointed out that struct net becomes overbloated and un-maintainable. There are two solutions: - provide a pointer to a network subsystem definition from struct net. This costs an additional dereferrence - place sub-system definition into the structure itself. This will speedup run-time access at the cost of recompilation time The second approach looks better for us. Other sub-systems will follow. Signed-off-by: Denis V.
