f246e4a17f - Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
  such abuse isn't really needed.  (And if we do need type information
  associated with a module then we should make it explicit and not
  use hacks.)

b376d47740 - Fixes for suspend/resume code (MPI-350)
- Cache temp. keys so they are preserved across suspend/resume (MPI-350)
- Reads and writes are real fast to the MPI-350 causing early timeouts so
  wait do some DELAYs to slow things down in the spin loops.
- Stream line setting RIDs when they are better to be set via another
  function
- Add better support for setting home key via "ifconfig an0 wepkey 9:<key>"

6cafe2646a Add support for MPI-350 the mini-pci Cisco Aironet card. This needs more
work.  The interface was gleaned from the Linux driver.  Currently only
one RX & one TX buffer are used.  Firmware support is not tested so for the
MPI-350 so it is disabled.  Signal cache and monitor mode are not supported
yet.  Signal cache is not supported since in encapsulation mode ethernet
frames are returned by the chip.  LAN monitor mode support will be added
shortly.  Thanks to Warner for the MPI-350 card he sent me.

Add support for RSSI map from PR kern/32880 which was incomplete.  Enhanced
with the ability to select the cache mode of raw, dbm or per-cent.

Clean up Signal/Noise/Quality structures and units with help from
Marco Molteni.

Change flash to use a malloc'ed buffer when needed.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

0d6fcb5c0e Fix bugs in the structure for rx_frame by making gap length one byte and
a packed array so sizeof work.  This broke RFMON mode and passing
up 802.11 packets.

The Linux emulation code was derived from the open source Linux driver to
maintain compatibility.

LEAP support is added, hints from Richard Johnson.  I've verified this
locally with PC350v42510.img firmware.  More bug fixing from Marco to
fix long passwords.

Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep
so it doesn't look like your system died during a flash update.

Install header files in /usr/include/dev/an

Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol.
This way you can manage 2 keys a little easier.  Map the home mode into
key 5.  Enhance ifconfig to dump the various configured SSIDs.  I use
a bunch of different ones and roam between them.  Use the syntax similar
to the WEP keys to deal with setting difference SSIDs.

Bump up up the Card capabilities RID since they added 2 bytes to it
in the latest firmware.  Thankfully we changed it from a terminal
failure so the card still worked but the driver whined.

Some cleanup patches from Marco Molteni.

9ed346bab0 Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

08812b3925 Implement MTX_RECURSE flag for mtx_init().
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.

The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.

The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.
