* Known Problems:
* The internal sysbus seems to be slow. So we often lose packets because of
* overruns while receiving from a fast remote host.
- * This can slow down TCP connections. Maybe the newer ni5210 cards are better.
- * my experience is, that if a machine sends with more than about 500-600K/s
- * the fifo/sysbus overflows.
