b84e866a18 Due to extreme bogusness in the pci bus layer, these drivers were
forced to do slightly bogus power state manipulation.  However, this
is one of those features that is preventing further progress, so mark
them as BURN_BIRDGES like I did for the drivers in sys/dev/...

This, like the other change, are a no-op unless you have BURN_BRIDGES
in your kernel.

214073e5e4 Use newly minted device_is_attached rather than device_is_alive to see
if attach succeeded.  device_is_alive just tells us that probe
succeeded.  Since we were using it to do things like detach net
interfaces, this caused problems when there were errors in the attach
routine.

693f4477b1 Revise attach/detach resource cleanup
- Unconditionally call *_stop() if device is in the tree. This is to
  prevent callouts from happening after the device is gone. Checks for
  bus_child_present() should be added in the future to keep from touching
  potentially non-existent hardware in *_detach().  Found by iedowse@.
- Always check for and free miibus children, even if the device is not in
  the tree since some failure cases could have gotten here.
- Call ether_ifdetach() in the irq setup failure case
- ti(4), xl(4): move ifmedia_init() calls to the beginning of attach so
  that ifmedia_removeall() can be unconditionally called on detach. There
  is no way to detect whether ifmedia has been initialized without using
  a separate variable (as tl(4) does).
- Add comments to indicate assumptions of code path

54f1f1d1e6 Clean up locking and resource management for pci/if_*
- Remove locking of the softc in the attach method, instead depending on
  bus_setup_intr being at the end of attach (delaying interrupt enable until
  after ether_ifattach is called)
- Call *_detach directly in the error case of attach, depending on checking
  in detach to only free resources that were allocated.  This puts all
  resource freeing in one place, avoiding thinkos that lead to memory leaks.
- Add bus_child_present check to calls to *_stop in the detach method to
  be sure hw is present before touching its registers.
- Remove bzero softc calls since device_t should do this for us.
- dc: move interrupt allocation back where it was before.  It was unnecessary
  to move it.  This reverts part of 1.88
- rl: move irq allocation before ether_ifattach.  Problems might have been
  caused by allocating the irq after enabling interrupts on the card.
- rl: call rl_stop before ether_ifdetach
- sf: call sf_stop before ether_ifdetach
- sis: add missed free of sis_tag
- sis: check errors from tag creation
- sis: move dmamem_alloc and dmamap_load to happen at same time as tag creation

f5eece3fb9 Change m_devget()'s outdated and unused `offset' argument to actually mean
something: offset into the first mbuf of the target chain before copying
the source data over.

Make drivers using m_devget() with a first argument "data - ETHER_ALIGN"
to use the offset argument to pass ETHER_ALIGN in. The way it was previously
done is potentially dangerous if the source data was at the top of a page
and the offset caused the previous page to be copied (if the
previous page has not yet been appropriately mapped).

The old `offset' argument in m_devget() is not used anywhere (it's always
0) and dates back to ~1995 (and earlier?) when support for ethernet trailers
existed. With that support gone, it was merely collecting dust.

68e691b2ab The sk driver developed a bug when the multicast code was changed to
use TAILQ macros. The sk_attach_xmac() routine calls sk_init_xmac()
before doing the transceiver probe, but *before* ether_ifattach()
is called. This causes sk_init_xmac() to call sk_setmulti(), which
tries to do a TAILQ_FOREACH(), which it can't do because ether_ifattach()
hasn't done a TAILQ_INIT() yet. This causes a NULL pointer dereference
and panic in sk_setmulti() at driver load/initialization time.

Fixed by calling ether_ifattach() before the MII probe.

The code in RELENG_4 still uses the old way of enumerating the
multicast list and doesn't have this problem. Yet.

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.

a5c4836d39 Replace the mbuf external reference counting code with something
that should be better.

The old code counted references to mbuf clusters by using the offset
of the cluster from the start of memory allocated for mbufs and
clusters as an index into an array of chars, which did the reference
counting. If the external storage was not a cluster then reference
counting had to be done by the code using that external storage.

NetBSD's system of linked lists of mbufs was cosidered, but Alfred
felt it would have locking issues when the kernel was made more
SMP friendly.

The system implimented uses a pool of unions to track external
storage. The union contains an int for counting the references and
a pointer for forming a free list. The reference counts are
incremented and decremented atomically and so should be SMP friendly.
This system can track reference counts for any sort of external
storage.

Access to the reference counting stuff is now through macros defined
in mbuf.h, so it should be easier to make changes to the system in
the future.

The possibility of storing the reference count in one of the
referencing mbufs was considered, but was rejected 'cos it would
often leave extra mbufs allocated. Storing the reference count in
the cluster was also considered, but because the external storage
may not be a cluster this isn't an option.

The size of the pool of reference counters is available in the
stats provided by "netstat -m".

bd80fa2c7f Reoganize/update the SysKonnect driver:
- Break out the support for the XMAC II's PHY into an miibus driver.

- Reorganize the probe/attach stuff using newbus. Each XMAC is now
  attached to the parent GEnesis controller using newbus. This is
  necessary since each XMAC must also have an attached miibus, and
  the miibus read/write register routines need to be able to get
  at the softc struct for each XMAC, not the one for the parent
  controller. This allows me to get rid of the grotty code I added
  for selecting the unit numbers for the ifnet interfaces: the unit
  numbers are now derived from the newbus-assigned unit numbers,
  which should track with the ifnet interface numbers. I think.
  At the very least, there should never be any collisions.

- Add support for the SK-9821 and SK-9822 1000baseTX adapters. Special
