There are too many platforms and they're all different as you already 
said. Common platforms will give you the possibility of having a few 
queues, so I will also investigate what the result would be of having 
three queues, one for LE, one for BE and one for rest, where LE gets 5% 
and the two other queues share the rest (getting half the bw each if both 
are congested).

This kind of setup would result in no congestion seen by rest of traffic 
even if BE and LE are fully congested.

If I set the LE drop profile to 1ms/2ms then it stopped working when there 
was BE congestion. I think this is not what one wants to happenn for 
normal customers, instead LE traffic should get some bandwidth even if 
it's a smallish single digit percentage of the total.
