[Cake] Exercising all cake tins in diffserv4 with flent

Hi All,
Maybe someone will find this useful: Attached is a flent config for
exercising all of cake's diffserv tins in diffserv4 mode. Very much
based on rrul, in essence it runs at least 1 tcp stream in each tin. 2
streams are used in each tin for upload, only 1 stream per tin for
download - I was interested in upload fairness between tins & flows
within tins in a 'full on, everyone competing for everything' type test.
Well, it's kept me entertained for a few minutes :-)
