For L2TP downstream traffic the IPv4 TOS is applied to the outer IPv4 
and inner IPv4 header.

The ``pps`` option supports also float numbers like 0.1, or 2.5 PPS and has 
priority over ``bps`` where second is only a helper to calculate the ``pps`` 
based on given ``bps`` and ``length``.

The options ``access-ipv4-source-address`` and ``access-ipv6-source-address`` 
are used to test the BNG RPF functionality with traffic send from source addresses 
different to those assigned to the client.
