* namespaces, the implementation is substantially simpler: packets are directly

*
* - CLOSED: no connection
* - SPLICE_ACCEPTED: accept() on the listening socket succeeded
* - SPLICE_CONNECT: connect() issued in the destination namespace
* - SPLICE_ESTABLISHED: connect() succeeded, packets are transferred
