Implementation from NetBSD. Ported via FreeBSD's version in trunk^Wlagg(4).
This is still work in progress. Tested with a HP ProCurve 3500.

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

1) remove multiple size queues, introduced as a stopgap.
2) decouple pages containing data from their mappings
3) only keep buffers mapped when they actually have to be mapped
(right now, this is when buffers are B_BUSY)
4) New functions to make a buffer busy, and release the busy flag
(buf_acquire and buf_release)
5) Move high/low water marks and statistics counters into a structure
6) Add a sysctl to retrieve buffer cache statistics
Tested in several variants and beat upon by bob and art for a year. run
accidentally on henning's nfs server for a few months...

near maximal (2^32) cycle times. These are useful for network
IDs in cases where there are negative consequences to ID prediction
and/or reuse.
Use the idgen32() functions to generate IPv6 IDs and NFS client/server
XIDs.

domain skip32.c from Greg Rose.

MPLS support partly based on the (abandoned?) AYAME project.
Basic LSR (Label Switch Router) functionality is present, but not fully
functional yet.
It is currently possible to insert entries in the LIB (Label Information Base)
with route(8), but setting the operation type is not supported yet.
Imported to allow more people to work on this in the coming weeks.

handshake protocols (both supplicant and authenticator state
machines) as defined in the IEEE 802.11i standard.
Software implementation of the TKIP (Temporal Key Integrity
Protocol) and CCMP (CTR with CBC-MAC Protocol) protocols.
This diff doesn't implement any of the 802.1X authentication
protocols and thus only PSK authentication (using pre-shared
keys) is currently supported.
In concrete terms, this adds support for WPA-PSK and WPA2-PSK
protocols, both in station and hostap modes.
The following drivers are marked as WPA-capable and should
work: bwi(4), malo(4), ral(4), iwn(4), wpi(4), ural(4),
rum(4), upgt(4), and zyd(4)
The following options have been added to ifconfig(8):
wpa, wpapsk, wpaprotos, wpaakms, wpaciphers, wpagroupcipher
wpa-psk(8) can be used to generate keys from passphrases.

uvideo(4) is a driver for USB video device class devices including webcams,
camcorders and other cameras.
video(4) is a device-independent layer that implements the V4L2 (Video for Linux Two)
API.
These drivers are *really* work in progress so don't even try to use them just yet,
because the driver still has some issues, even if it can be used to capture simple
MJPEG videos.

agp and drm need to use the same memory mapping, the best way to deal
with that is to allow them to share (that's coming later), for this to
work cleanly we move the attach point of agp.
Ideally most agp drivers would attach at pchb, with only agp_i810
(and any that work similarly) attaching at vga, but this will do for
now.

radio clocks can transmit over serial ports. This is implemented as a
line discipline similar to nmea(4) and provides a timedelta sensor.
See http://www.meinberg.de/english/specs/timestr.htm for details on the
MSTS format.
ldattach(8) is extended to support the "msts" line discipline and two stopbits
(which some radio clocks, e.g. the C51 use). Do a "make includes" before your
next system build.
Initially from Maurice Janssen based on nmea(4). "go for it" deraadt

This is the kernel part necessary for DRI support in X. Disabled for now
because it still has a few bugs, but now I can work on it in tree. Also
requires the requisite bits in X, which are currently under discussion
on how to deal with them with privsep. ported from a combination of the
free and netbsd implementations.
Known bugs:
1) only the first occurence of X in any session will have dri, after
that something prevents it working.
2) if the machine does not have a dri capable card, the kernel panics.
Something's up in one of the probe functions. I haven't been able to
find it though.
3) radeon cards need to be forced to use PCI mode otherwise they get
into an infinite loop.
This is known to at least kinda work with SiS, radeons in pci mode and
intel cards.
ok deraadt, kinda ok art, a few other people had a quick look.

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.
There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.
Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

decide which files must be pulled into the kernel. Also conditionalize
the pulling of those files based on the COMPAT_* options.

Attaches as 'ral' as it shares the PCI and CardBus frontends with
RT2560 and RT2661 though it is actually a separate driver.
Requires a firmware that can't be redistributed with the base system
due to license restrictions (exact same license as iwn(4) firmware).
The 802.11n capabilities not yet supported (except MIMO).
Great thanks to Sam Fourman Jr for donating hardware.

itself, and thus demands the unconditional inclusion of crypto/arc4.c

- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)
there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.
