complete this driver.

o Add rid/res members to pccard_function

o map memory properly in scan_cis (almost, see XXX for more work)
o manage ccr.
o remove bogus comment I added about touching the ccr being a layering

o More function prototyping

1) Fastpath deletions. When a file is being deleted, check to see if it
was so recently created that its inode has not yet been written to
disk. If so, the delete can proceed to immediately free the inode.
2) Background writes: No file or block allocations can be done while the
bitmap is being written to disk. To avoid these stalls, the bitmap is
copied to another buffer which is written thus leaving the original
available for futher allocations.
3) Link count tracking. Constantly track the difference in i_effnlink and
i_nlink so that inodes that have had no change other than i_effnlink
need not be written.
4) Identify buffers with rollback dependencies so that the buffer flushing

syncer process starts running the worklist, it wants to delete
lots of files. It does this by VFS_VGET'ing the vnodes, clearing
the blocks in them and bdwrite'ing the buffer. It can process close
to a thousand files per second which generates a large number of
dirty buffers. So, giving it special priviledge at the buffer trough

buffer to proceed and if the syncer has used every last one up,

Once it is unlocked, other operations may slip in that could make

hinted at in the previous config(8) commits. I've spoken about this with
a few people and after the initial suprise wore off they thought it wasn't
a bad idea. The upshot of it is that all the files*, Makefile*, options*
files are all right next to each other in the hope that people making
changes to one set will remember the others.
Note, config(8) looks to sys/conf first, and falls back to sys/$mach/conf
still, so this doesn't stop people working in subdirs for new platforms.
But once it's in the tree it can be moved next to the other files so that
the non-i386 platforms are (hopefully) treated a little better than as if
they were "second class" ports.
This does not change any user editable files. the config program is
still run in the same directory as before, the per-platform files
(GENERIC, LINT etc) are still in the same place.

- Fix a typo in the SYMBIOS NVRAM layout structure and add field and

- Report to XPT PIM_NOBUSRESET and PIM_SCANHILO if set by user in NVRAM.
- Negotiate SYNC immediately after WIDE response from the target as

- Remove some misleading comment about CmdQue handling by CAM.
- Apply correctly the MAX_WIDE and MAX_OFFS driver options.

Removed an unused forward declaration and an unused include.

now you can dynamically create rate-limited queues for different
flows using masks on dst/src IP, port and protocols.
Read the ipfw(8) manpage for details and examples.
Restructure the internals of the traffic shaper to use heaps,
so that it manages efficiently large number of queues.
Fix a bug which was present in the previous versions which could
cause, under certain unfrequent conditions, to send out very large
bursts of traffic.
All in all, this new code is much cleaner than the previous one and
should also perform better.

It seems that the IDE system uses 0x3f6 for itself, which conflicts with
fdc's default 0x3f0-3f7 allocation range. Sigh. Work around this.
Use bus_set_resource() rather than allocating specific areas, it makes
the code a little cleaner.

Note: the .INF file for LinkSys's driver says the vendor ID is 0x66b,
however this does not agree with the vendor ID listed for LinkSys in
the company list from www.usb.org. In fact, 0x66b doesn't seem to appear
in the company list at all. Furthermore, this same vendor ID crops
up in some of the D-Link .INF files. Frankly I don't know what the heck
is going on here, but I need to add 0x66b to usbdevs and call it
something, so here we are.
certain PHY addresses in aue_miibus_readreg(). Not all adapters based
on the Pegasus chip may have their PHYs wired for the same MII bus
addresses: the logic that I used for my ADMtek eval board might not
apply to other adapters, so make sure to only use it if this is really
an ADMtek eval board (check the vendor/device ID).
This will hopefully make the LinkSys USB100TX adapter work correctly.

Make the SRAM dump output a little prettier.
aic7xxx.c:
Store all SG entries into our SG array in kernel space.
This makes data-overrun and other error reporting more
useful as we can dump all SG entries. In the past,
we only stored the SG entries that the sequencer might
need to access, which meant we skipped the first element
that is embedded into the SCB.
Add a table of chip strings and replace ugly switch
statements with table lookups.
Add a table with bus phase strings and message reponses
to parity errors in those phases. Use the table to
pretty print bus phase messages as well as collapse
another switch statement.
Fix a bug in target mode that could cause us to unpause
the sequencer early in bus reset processing.
Add the 80MHz/DT mode into our syncrate table. This
rate is not yet used or enabled.
Correct some comments, clean up some code...
aic7xxx.h:
Add U160 controller feature information.
Add some more bit fields for various SEEPROM formats.
aic7xxx.reg:
Add U160 register and register bit definitions.
aic7xxx.seq:
Make phasemis state tracking more straight forward. This
avoids the consumption of SINDEX which is a very useful register.
For the U160 chips, you must use the 'mov' instruction to
update DFCNTRL. Using 'or' to set the PRELOADED bit is
completely ineffective.

Correct a termination buglet for the 2940UW-Pro.
Be more paranoid in how we probe and enable external ram, fast external

20ns and 8bit SRAM parts.
Perform initial setup for the DT feature on cards that support it.
Factorize and clean up code. Use tables where it makes sense, etc.
Add some delays in dealing with the board control logic. I've never
seen this code fail, but with the ever increasing speed of processors,
its better to insert deterministic delays just to be safe. This stuff
is only touched during probe and attach, so the extra delay is of no
concern.
ethernet adapters that are supported by the aue and kue drivers.
There are actually a couple more out there from Accton, Asante and
EXP Computer, however I was not able to find any Windows device
drivers for these on their servers, and hence could not harvest
their vendor/device ID info. If somebody has one of these things
and can look in the .inf file that comes with the Windows driver,
I'd appreciate knowing what it says for 'VID' and 'PID.'
Additional adapters include: the D-Link DSB-650 and DSB-650TX, the
SMC 2102USB, 2104USB and 2202USB, the ATen UC10T, and the Netgear EA101.
These are all mentioned in the man pages, relnotes and LINT.
Also correct the date in the kue(4) man page. I wrote this thing
