controllers (PDC203** PDC206**).
This also adds preliminary support for the Promise SX4/SX4000 but *only*
as a "normal" Promise ATA controller (ATA RAID's are supported though
but only RAID0, RAID1 and RAID0+1).
This cuts off yet another 5-8% of the command overhead on promise controllers,
making them the fastest we have ever had support for.
Work is now continuing to add support for this in ATA RAID, to accellerate
ATA RAID quite a bit on these controllers, and especially the SX4/SX4000
series as they have quite a few tricks in there..
This commit also adds a few fixes to the SATA code needed for proper support.
Alignment for pccards should also be treated in a similar way that
we tread it for cardbus cards.

# This is also necessary to make the CIS reading work.

(1) Align to 64k for the CIS. Some cards don't like it when we aren't
aligned to a 64k boundary. I can't find anything in the standard
that requires this, but I have 1/2 dozen cards that won't work at
all unless I enable this.
(2) Sleep 1s before scanning the CIS. This may be a nop, but has little
harm.
(3) The CIS can be up to 4k in some weird, odd-ball edge cases. Since we
have limiters for when that's not the case, it does no harm to increase
it to 4k.

Fix and off by one error that caused unnecessary filtering of valid

ICH3 controllers have with the new code, it does restore the former

# I don't think this will fix any real bugs...
Xircom had an unfortunate habit of re-using PCMCIA IDs for quite different
cards - the xe driver knows about this and uses the first byte of 'extra'
PCMCIA ID info to identify cards with ambiguous IDs.

returning.
- When providing resources via ndis_query_resources(), uses the
computed rsclen when using bcopy() to copy out the resource data
rather than the caller-supplied buffer length.
- Avoid using ndis_reset_nic() in if_ndis.c unless we really need
to reset the NIC because of a problem.
- Allow interrupts to be fielded during ndis_attach(), at least
as far as allowing ndis_isr() and ndis_intrhand() to run.
- Use ndis_80211_rates_ex when probing for supported rates. Technically,
this isn't supposed to work since, although Microsoft added the extended
rate structure with the NDIS 5.1 update, the spec still says that
the OID_802_11_SUPPORTED_RATES OID uses ndis_80211_rates. In spite of
this, it appears some drivers use it anyway.
- When adding in our guessed rates, check to see if they already exist
so that we avoid any duplicates.
- Add a printf() to ndis_open_file() that alerts the user when a
driver attempts to open a file under /compat/ndis.
With these changes, I can get the driver for the SMC 2802W 54g PCI
card to load and run. This board uses a Prism54G chip. Note that in
order for this driver to work, you must place the supplied smc2802w.arm
firmware image under /compat/ndis. (The firmware is not resident on
the device.)
Note that this should also allow the 3Com 3CRWE154G72 card to work
as well; as far as I can tell, these cards also use a Prism54G chip.
without the (defunct) isa compatibility shims. The new-bus-specific
parts are very similar to the ones for the pci probe and attach.
This was held up too long waiting for a repo copy to src/sys/dev/cy,
so I decided to fix the files in their old place. This gives easier
to read and merge diffs anyway.
The "count" line in src/sys/conf/files won't be changed until after
the repo copy, so old kernel configs that specify a count need not be
(and must not be) changed until then. The count is just ignored in
the driver. One unfinished detail is dynamic allocation of arrays
with <count> and (<count> * 32) entries, and iteration over the arrays.
This is now kludged with a fixed count of 10 (up to 10 cards with up
to 32 ports each).

common attach function so that the lock gets initialized in all cases.
This fixes breakage of the initialization of the lock in the pci case
in rev.1.135 (between the releases of 5.1 and 5.2). The lock is only
used in the SMP case, so this bug was not always fatal.
