The packet driver interface seems to degrade performace by only a few percent
when compared against a linked-in driver.

I have pumped more than 2500 packets per second through a packet driver
I wrote for the TRW board.

Someone who is clever could put the bulk of the driver out in EMS memory
or on a mildely smart board, keeping only the first level interface
code in the critical 640K zone.
