FreeBSD's tcp/udp traffic generator
netreceive is a UDP packet sink; packets received are copied to user
space and discarded.

netsend is a UDP packet generator, sending at a rate configured on
the command line.

netblast is a UDP packet generator, sending at as high a rate as
possible.

These tools are repackaged from the FreeBSD source tree
(/usr/src/tools/tools/netrate).
