As well as marking flows this indirectly marks the ipv4 routing cache
as every routing entry contains a flow.
It is useful to add the network namespace into flows as frequently
the routing information for ingoing and outgoing network packets is
collected into a flow structure which is then used for several functions
as it sorts out what is going on.
Changes from v1:
- remove flow.h dependency from net_namespace.h
