Bandwidth Queuing on Asymmetrical Connections?

[Jordan Geoghegan]

Hi folks, I was wondering how one goes about maintaining separate upload 
and download queues in pf. I have been playing with various combinations 
and I can't seem to get both queues to apply simultaneously.

For example, I have a 150 down 15 up connection. I want to limit a 
specific device on the network to 100 down and 10 up. I can't for the 
life of me figure out how to make this apply. I either end up setting a 
10 megabit limit or 100. How do the pf gurus manage their asymmetrical 
connections?
