f7167d3e91 Move enable/disable 16bit access routines into if_ed. Slightly
pessmize the error recover path through edintr by calling these
functions, rather than expanding it inline.  This error path already
does a lot in it, so an extra function call will be lost in the noise.
It also happens rarely.

6cc7bd9464 1. Revert back to the way the older driver handled XPT_PATH_INQ. This seems to
fix the problem with device discovery seen by some people.
2. Change to make 3ware CLI/3DM work on amd64.
3. Fix a potential problem that could cause the driver to do strlen(NULL) when
   using older firmware.

f2566fc59b Extricate probing of the gwether card (Gateway AT) from the middle of
probing the novell ne[12]000 cards.  It should be its own thing, ala
how we do the dl100xx support doing its own thing at the right time.
For the moment, it is just a function, which makes the mainline of the
generic probe easier to follow.

Also, correct a couple of comments that looked wrong.

# there may be a bug in setting up gwether, in that we set
# sc->rec_page_stop based on memsize, rather than sc->mem_size, so if
# these two are different, then the rec_page_stop will be wrong.  I'm
# hesitant to fix it without real hardware to test with.  Since
# gwether isn't in the hardware list of the man page nor in the commit
# messages, it is hard to know for sure.

969eaf2179 Break out obscure ISA cards into their own files, as well as ne2000
and wd80x3 support.  Make the obscure ISA cards optional, and add
those options to NOTES on i386 (note: the ifdef around the whole code
is for module building).  Tweak pc98 ed support to include wd80x3 too.
Add goo for alpha too.

The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that
is).  I couldn't find any of these for sale on ebay, so they are
untested.  If you have one of these cards, and send it to me, I'll
ensure that you have no future problems with it...

Minor cleanups as well by using functions rather than cut and paste
code for some probing operations (where the function call overhead is
lost in the noise).

Remove use of kvtop, since they aren't required anymore.  This driver
needs to get its memory mapped act together, however, and use bus
space.  It doesn't right now.

This reduces the size of if_ed.ko from about 51k to 33k on my laptop.

940e7b9e51 o Remove duplicate LINKSYS ETHERFAST entry.
o The COMBO_ECARD comes in many flavors, it seems, so probe both the DL10019
  and the AX88x90 on it.  Since this seems to work with no ill effects, maybe
  the probing should happen more generally rather than being table driven.
  Need to think more about this.
o Remove PCM100 because it is duplicative (the ETHERFAST is the pcm100 and
  apparently has the same IDs).  It was here for NetBSD because they match
  up an expected MAC address OID, but since we don't bother with that, we
  don't need to be so finely discriminating.

b545a3b822 Next step on the road to IRPs: create and use an imitation of the
Windows DRIVER_OBJECT and DEVICE_OBJECT mechanism so that we can
simulate driver stacking.

In Windows, each loaded driver image is attached to a DRIVER_OBJECT
structure. Windows uses the registry to match up a given vendor/device
ID combination with a corresponding DRIVER_OBJECT. When a driver image
is first loaded, its DriverEntry() routine is invoked, which sets up
the AddDevice() function pointer in the DRIVER_OBJECT and creates
a dispatch table (based on IRP major codes). When a Windows bus driver
detects a new device, it creates a Physical Device Object (PDO) for
it. This is a DEVICE_OBJECT structure, with semantics analagous to
that of a device_t in FreeBSD. The Windows PNP manager will invoke
the driver's AddDevice() function and pass it pointers to the DRIVER_OBJECT
and the PDO.

The AddDevice() function then creates a new DRIVER_OBJECT structure of
its own. This is known as the Functional Device Object (FDO) and
corresponds roughly to a private softc instance. The driver uses
IoAttachDeviceToDeviceStack() to add this device object to the
driver stack for this PDO. Subsequent drivers (called filter drivers
in Windows-speak) can be loaded which add themselves to the stack.
When someone issues an IRP to a device, it travel along the stack
passing through several possible filter drivers until it reaches
the functional driver (which actually knows how to talk to the hardware)
at which point it will be completed. This is how Windows achieves
driver layering.

Project Evil now simulates most of this. if_ndis now has a modevent
handler which will use MOD_LOAD and MOD_UNLOAD events to drive the
creation and destruction of DRIVER_OBJECTs. (The load event also
does the relocation/dynalinking of the image.) We don't have a registry,
so the DRIVER_OBJECTS are stored in a linked list for now. Eventually,
the list entry will contain the vendor/device ID list extracted from
the .INF file. When ndis_probe() is called and detectes a supported
device, it will create a PDO for the device instance and attach it
to the DRIVER_OBJECT just as in Windows. ndis_attach() will then call
our NdisAddDevice() handler to create the FDO. The NDIS miniport block
is now a device extension hung off the FDO, just as it is in Windows.
The miniport characteristics table is now an extension hung off the
DRIVER_OBJECT as well (the characteristics are the same for all devices
handled by a given driver, so they don't need to be per-instance.)
We also do an IoAttachDeviceToDeviceStack() to put the FDO on the
stack for the PDO. There are a couple of fake bus drivers created
for the PCI and pccard buses. Eventually, there will be one for USB,
which will actually accept USB IRP.s

Things should still work just as before, only now we do things in
the proper order and maintain the correct framework to support passing
IRPs between drivers.

Various changes:

- corrected the comments about IRQL handling in subr_hal.c to more
  accurately reflect reality
- update ndiscvt to make the drv_data symbol in ndis_driver_data.h a
  global so that if_ndis_pci.o and/or if_ndis_pccard.o can see it.
- Obtain the softc pointer from the miniport block by referencing
  the PDO rather than a private pointer of our own (nmb_ifp is no
  longer used)
- implement IoAttachDeviceToDeviceStack(), IoDetachDevice(),
  IoGetAttachedDevice(), IoAllocateDriverObjectExtension(),
  IoGetDriverObjectExtension(), IoCreateDevice(), IoDeleteDevice(),
  IoAllocateIrp(), IoReuseIrp(), IoMakeAssociatedIrp(), IoFreeIrp(),
  IoInitializeIrp()
- fix a few mistakes in the driver_object and device_object definitions
- add a new module, kern_windrv.c, to handle the driver registration
  and relocation/dynalinkign duties (which don't really belong in
  kern_ndis.c).
- made ndis_block and ndis_chars in the ndis_softc stucture pointers
  and modified all references to it
- fixed NdisMRegisterMiniport() and NdisInitializeWrapper() so they
  work correctly with the new driver_object mechanism
- changed ndis_attach() to call NdisAddDevice() instead of ndis_load_driver()
  (which is now deprecated)
- used ExAllocatePoolWithTag()/ExFreePool() in lookaside list routines
  instead of kludged up alloc/free routines
- added kern_windrv.c to sys/modules/ndis/Makefile and files.i386.

9d512034e3 Make it possible to unload ed. Move the ed_pccard_detach routine to

Since I don't actually have any non-pccard ed hardware I can test
with, I've only tested with my pccards.

More improvements in this area likely are possible.

very bad.

108663cc87 ccs is a size_t. RAY_CCS_INDEX takes ccs and does math on it,
resulting in a size_t due to C's rules of arithmetic.  Rather than
bogusly cast the result to a uint8_t, fix the printf format specifier
to have a 'z' modifier which tells the compiler that the sizes really
do match.

It turns out that change 1.75 was incorrect to assume that this
'really' was a 8bit quantity.  It isn't.  Although the hardware
appears to limit things to < 256, it would be a bug that should be
caught by debug printf it it were.  Casting it to uint8_t would have
lost this useful information.

Aslo add 'z' to a nearby debug statement that's never compiled in.

3cc2f17689 Notify the OS that we're taking over Px states in acpi_perf(4) instead of
doing it in the cpu driver.  The previous code was incorrect anyway since
this value controls Px states, not throttling as the comment said.  Since
we didn't support Px states before, there was no impact.  Also, note that
we delay the write to SMI_CMD until after booting is complete since it
sometimes triggers a change in the frequency and we want to have all
drivers ready to detect/handle this.
