[Click] Click with Weighted Round Robin

[Brecht Vermeulen]

Hi,

as far as I know ScheduleInfo can only be used to change the ratios in 
which scheduled elements in click are run.

The clue is however 'scheduled elements'. These are elements which are 
on Click's internal scheduler's list and are e.g. PollDevice, 
FromDevice, ToDevice, InfiniteSource. (no queues, no RoundRobinSched)

Maybe I miss something but I don't see how flux is defined ?

Nevertheless, if flux is a todevice or so, I don't think you can specify 
the ports separately in the ScheduleInfo. (does this actually work 
without errors on configuration ?)

I don't think you can easily achieve what you want with ScheduleInfo, 
but maybe the StrideSched 
(http://www.pdos.lcs.mit.edu/click/doc/StrideSched.n.html) can be used 
or you can write an own element.

regards,
Brecht
