The performance improvement is measured on AMD970 operating at 800Mhz

- Don't refill and allocate new packets for each transmission, instead
a set of pregenerated packets are used.
- Use NIC driver's "txeof" to tick out more packets instead of bindly

These above two modifications give me ~200Kpps (710Kpps -> 910Kpps)

/bin/mv: Sync with FreeBSD
1. Utilize central <paths.h> header
2. Meet posix spec for moving directory to existing non-empty directory
3. Meet posix spec for not moving directory over a file
4. Don't chop IO into pieces, use MAXPHYS
5. Add -h flag (similar to ln -h flag)
6. Test for input_is_terminal
7. Regression test added.
DETAILS
==========================================================================
1. remove pathnames.h file and add _PATH_RM to paths.h
2. Moving a directory to an existing non-empty directory will now fail as
required.
3. Prior to change this test past, but after change it failed on
cross-link devices. Original code added to check for case and return
-1 for the cross-link case.
4. Read files in one block and improve warn messages.
5. Using -h flag will force mv to treat a symbolic link to a directory
for the target as a symbolic link instead of a directory. This makes
it possible to atomically update a symbolic link using rename().
6. POSIX requires this behavior:
if (exists and (NOT f_options) AND
((not_writable AND input_is_terminal) OR i_option)) then
prompt
This behavior was implemented.
7. Passes all tests in suite. Prior to change it failed 2 of 32 tests.

/bin/rm: fix removing symlinks with uchg/uappnd set
One error case described in FreeBSD PR bin/111226:
/bin/rm when running as super user and failing to unlink a
UF_APPEND|UF_IMMUTABLE protected symbolic link will reset the
UF_APPEND and UF_IMMUTABLE flags on the symbolic link's target (if
that target exists) - an object that /bin/rm should not touch! (Quote
from SUSv3: "The rm utility removes symbolic links themselves, not
the files they refer to, as a consequence of the dependence on the
unlink() functionality").
There was a failure case for /usr/bin/find as well, but swildner
recently synchronized find with FreeBSD and fixed that one.

libc/fts: Use O_CLOEXEC for internal file descriptors
Because fts keeps internal file descriptors open across calls, making such
descriptors close-on-exec helps not only multi-threaded applications but
also single-threaded applications.
In particular, this prevents passing a temporary file descriptor for saving
the current directory to processes created via find -exec.

init(8): Resurrect kern.shutdown_timeout as kern.init_shutdown_timeout.
Taken from FreeBSD. Quoting their commit msg:
Fix system shutdown timeout handling by again supporting longer running
shutdown procedures (which have a duration of more than 120 seconds).
We have two user-space affecting shutdown timeouts: a "soft" one in
/etc/rc.shutdown and a "hard" one in init(8). The first one can be
configured via /etc/rc.conf variable "rcshutdown_timeout" and defaults
to 30 seconds. The second one was originally (in 1998) intended to be
configured via sysctl(8) variable "kern.shutdown_timeout" and defaults
to 120 seconds.
Unfortunately, the "kern.shutdown_timeout" was declared "unused" in 1999
(as it obviously is actually not used within the kernel itself) and
hence was intentionally but misleadingly removed in revision 1.107 from
init_main.c. Kernel sysctl(8) variables are certainly a wrong way to
control user-space processes in general, but in this particular case the
sysctl(8) variable should have remained as it supports init(8), which
isn't passed command line flags (which in turn could have been set via
/etc/rc.conf), etc.
As there is already a similar "kern.init_path" sysctl(8) variable which
directly affects init(8), resurrect the init(8) shutdown timeout under
sysctl(8) variable "kern.init_shutdown_timeout". But this time document
it as being intentionally unused within the kernel and used by init(8).
Also document it in the manpages init(8) and rc.conf(5).
