net: pppoe - introduce net-namespace functionality
- each net-namespace for pppoe module is having own
hash table and appropriate locks wich are allocated
at time of namespace intialization. It requires about
140 bytes of memory for every new namespace but such
approach allow us to escape from hash chains growing
and additional lock contends (especially in SMP environment).
- pppox code allows to create per-namespace sockets for
PX_PROTO_OE protocol only (since at this moment support
for pppol2tp net-namespace is not implemented yet).
