This is a port of Jason Thorpe's kttcp tool for testing network
performance for in-kernel applications (like NFS). The tool consists
of a loadable module and a small user-mode application. Beware
that you should match the kernel module to the kernel it is to be
used with. By default SYSDIR is set to /usr/src/sys in Makefile.
You may want to change that.
To use the tool do something like on each of two machines:
1. make
2. su; make install (installs module and kttcp in /usr/local/bin)
3. kldload kttcp
Then:
4. kttcp -r on one machine
5. kttcp -t foo on the other machine, where foo is the
machine where #4 was done.
kttcp w/o arguments gives usage. Otherwise the source is your
friend. Beware that the kernel code must mimic soreceive and sosend
for results to be meaningful.
