Simple stuff
------------
Split _download up so that the MIB settings are in their own functions.
Made "tx completed but status is ..." a recoverable error
Cut down verbosity of "unloaded" messages
Moved ccs_free and com_runq from intr_ccs to ecf_done and runq_done
to avoid embarasing mistakes and waits.
Merged runq_add and runq_arr into one and called it runq_add
Made RAY_COM_DUMP a real debug called RAY_DCOM
Consistnet debugging around tsleeps.
Use bus_activate_resource for attr/cm mapping, and set the flags
correctly in the allocation routines (needs more hacks to
sys/pccard/pcic.c)
com_malloc is now seperated from the comq initialization. This was
done whilst trying to set automatic variables for the comqs.
Harder Stuff
------------
As part of the IFF_RUNNING fixes, remove the panic in runq if we are
not running.
Change, again, runq_add. This time we don't do any cleaning up
if there were errors. This is so that callers get the chance
to re-try (not that I ever see it being used).
In runq_add, only sleep when there is something to sleep on!
ioctl locking routines, stolen from awi.c but not used
Hardest Stuff
-------------
Dealing with serialing ioctls correctly means that we must QUEUE
changes to IFF_RUNNING and check it in the QUEUED commands, not
in the user commands. Whilst simple to state, it took a few
hours of head scratching to get it right. The realisation was that
I only have to guarantee that sub-commands from a single process
are serialised and "atomic", and that they check the status of the
interface flags when invoked and not when they are queued.
Another way of looking at it, is that the driver's state is stored
in the runq and the IFF_RUNNING flag. These must be changed together.
What this means practically, is that IFF_RUNNING is set after
we have started/joined/associated with a network. And it is
cleared by ray_stop via the runq so that unfinsished commands are
not distrupted.
I still have to fix up promisc, upp/repparams and mcast.
Oh yeah, stop is essentially a noop in that it only
changes IFF_RUNNING
- Get rid of a fiew uselessly `long' variables
and casts to `long'.
- Estimate the PCI clock for all chips, except
C1010 for now (we should do that for each PCI BUS)
- Refine a couple of C1010 errata work-arounds.
- For now, make sure AIP generation is disabled
for the C1010-66.
"options COMPAT_OLDPCI". This option already existed, but now also tidies
up the declarations in #include <pci/pci*.h>. It is amazing how much stuff

and does not require that evil list of drivers in isa_compat.h.
It uses the same strategy that pci drivers use, namely a
COMPAT_ISA_DRIVER() macro that creates the glue on the fly.
Theoretically old-style isa drivers should be preloadable now.
all other modes not set ALKED flag and it means that CapsLock always turned
off for them.
Real bug example is X11 which never turn on CapsLock with Russian keyboard.

Only PCI and on-board ISA peripherials are supported at this time.
This support has been only lightly tested due to a lack of response to my
call for testers on the freebsd-alpha mailing list. It works quite well
on the one AS2100 on which it has been tested, but it may not work on
an AS2100A and should therefore be regarded as experimental.
- Go ahead and use 'lgdt' again instead of hand-assembling the instruction.
During testing this code worked fine. If for some reason a 32-bit offset
is needed, 'lgdtl' should be used instead of reverting to manual machine
code.

buzy, only search upwards for a free slot to use..
This broke unit numbering on ATA systems where PCI attached controllers
come before the mainboard ones...

m_adj() and then check the resulting mbuf for misalignment, copying
backwards to align the mbuf if required.
This fixes a longstanding problem where an mbuf which would have been
properly aligned after an m_adj() was being misaligned and causing an
unaligned access trap in ip_input(). This bug only triggered when booting
diskless.

more frequently than the core part of the sio driver, it might

This (I believe) is the cause of the XFree86 startup and/or mptable(8)
panics when programs were reading from /dev/mem at non-page-aligned
offsets. The offsets were being converted into random page flags in the
page tables. :-( (including PG_PS = 4MB page size)

Minor cosmetics.
with the new binutils. Now that we have a decent assembler, all the old
m4 macros are no longer needed. Instead, straight assembly can be used
since as(1) now understands 16-bit addressing, branches, etc. Also,
several bugs have been fixed in as(1), allowing boot0.s to be further
cleaned up.
CAPACITY operation. SCSI-3 mandates this to be 2048, but some older
drives like my old Plasmon CD-R report weird numbers between 2048 and
up to 2352 bytes depending on the mode of the last track etc. This in
turn confuses stuff like the slice code since it refuses to work with
devices that do not have a blocksize which is a multiple of 512 bytes.
