A slightly older version was checked into FreeBSD on Oct 31 2002 and
converted for -current.  Attached is what we're running.  Feel free to
forward me any bug reports, especially if they included fixes.

This is a netgraph module that we have code in TCL to drive to create
high transmit rate for arbitrary packets. You can achieve about
half of gigabit rate for 64-byte packets with this on a broadcom
bge or intel em card [about 800Kpps].
