History
Matthew N. Dodd 2ff4e76374 Fix the performance problems I caused by setting ifq_maxlen to 8. 
Use IFQ_MAXLEN instead.  This seemed like a good idea at the time since
most 3c509s have all of 2k for their TX fifo.  My intention was to revisit
ifq_maxlen and auto-scale it or something.

I've got some tweaks that move the TX speed up to the RX speed but I've
got to groom them from the mess I've made of my source tree.
