It did help me understand the consequences of the different approaches.
I'm still in favour of putting the patches in, but I've hacked up a
small multiqueue simulator device and to my big surprise my testing
showed that Jamal's suggestion of using a single queue state seems to
work better than I expected. But I've been doing mostly testing of
the device itself up to now with very simple traffic patterns (mostly
just "flood all queues"), so I'll try to get some real results tomorrow.
