I thought about doing just that but then I realized that there would
be a number of issues.

First if I just set the skb->queue_mapping for the packet without
moving it to a qdisc dedicated to that tx queue I run into
head-of-line issues since multiple qdiscs will stop if holding packets
for a single tx queue that is full.  That is over come in this patch
by the fact that each qdisc has a specific fifo per tx queue.

Such fifos could be configured using 'tc' commands just
as easily.

Look, I know what you're trying to do is possible with at
best minor tweaks.  So don't press your luck listing how
impossible it is :-)
