thorpej 473e69750b This is the "kttcp" network throughput testing pseudo-device. From
the block comment at the top of the file:

      This module provides kernel support for testing network
      throughput from the perspective of the kernel.  It is
      similar in spirit to the classic ttcp network benchmark
      program, the main difference being that with kttcp, the
      kernel is the source and sink of the data.

      Testing like this is useful for a few reasons:

      1. This allows us to know what kind of performance we can
         expect from network applications that run in the kernel
         space, such as the NFS server or the NFS client.  These
         applications don't have to move the data to/from userspace,
         and so benchmark programs which run in userspace don't
         give us an accurate model.

      2. Since data received is just thrown away, the receiver
         is very fast.  This can provide better exercise for the
         sender at the other end.

      3. Since the NetBSD kernel currently uses a run-to-completion
         scheduling model, kttcp provides a benchmark model where
         preemption of the benchmark program is not an issue.

There is a companion "kttcp" user program which uses the kttcp
pseudo-device.

Largely written by Frank van der Linden, with some modifications
from me.

jdolecek 745ab257dc Put back all header files defining ioctls 2001-04-11 19:07:36 +00:00
jdolecek 372e5956ef Only install headers which are actually used by our userland. This
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
