I might be going about this the wrong way, but, this is ultimately what
I'm trying to do. One queue has guaranteed 3Mb, another has a
guaranteed 4Mb, another has 3Mb guarantee, which leaves about 90Mb as a
pool for all of them. If they are backlogged, I want the first 2 queues
to be able to utilize the entire 90Mb, and the 3rd queue should be able
to utilize about 25Mb of it. This is a simplified example of what I
sent earlier. But if I can do this, I can accomplish what I'm trying to
and build off it later.
