1. you should generate packets (way) faster than the card is able
to handle them;
2. the network card itself might be able to queue multiple packets in
the "transmit ring";
Closer inspection revealed that both the ifnet ifqueues as well as the
driver transmission chain are always empty upon enqueue/dequeue. Thus, even
though my fancy queuing code is executed, it has no effect, since there
never are any queues.

POSIX idle-time CPU scheduler for other resource types, one being network
I/O. The basic idea is to substitute two-level queues for the standard
ones. I'm seeing some unexpected things (explained below), but let me
