Add a delay before reading the number of ports from the controller to
avoid getting 0 from it.

A first stab at support for isochronous transfers.
===================================================================
Caveats:
The new savecore program is not complete in the sense that it emulates
enough of the old savecores features to do the job, but implements none
of the options yet.
I would appreciate if a userland hacker could help me out getting savecore
to do what we want it to do from a users point of view, compression,
email-notification, space reservation etc etc. (send me email if
you are interested).
Currently, savecore will scan all devices marked as "swap" or "dump" in
/etc/fstab _or_ any devices specified on the command-line.
All architectures but i386 lack an implementation of dumpsys(), but
looking at the i386 version it should be trivial for anybody familiar
with the platform(s) to provide this function.
Documentation is quite sparse at this time, more to come.
Details:
ATA and SCSI drivers should work as the dump formatting code has been
removed. The IDA, TWE and AAC have not yet been converted.
Dumpon now opens the device and uses ioctl(DIOCGKERNELDUMP) to set
the device as dumpdev. To implement the "off" argument, /dev/null
is used as the device.
Savecore will fail if handed any options since they are not (yet)
implemented. All devices marked "dump" or "swap" in /etc/fstab
will be scanned and dumps found will be saved to diskfiles
named from the MD5 hash of the header record. The header record
is dumped in readable format in the .info file. The kernel
is not saved. Only complete dumps will be saved.
All maintainer rights for this code are disclaimed: feel free to
improve and extend.

have ripped all the i386 specific formatting code from their
dump routines. Due to the potential for trashing disks, I did
not want to do this "blind".
(65536 * 32 - 1), but MAKEDEV only supports up to (32 * 32 -1). Device
names use the unit number in base 32 for all "digits".
This required fixing an old bug in MAKEDEV:ttyminor(). Its arg was the
global $unit instead of $1.

measured accurately for periodic interrupts provided the interrupts
don't need to be serviced very quickly to keep their period almost
constant. sio output interrupts have this property (interrupt service
can be delayed for up to 1 character time without the period changing).
This is non-optional and undocumented so that it can be added and
removed easily. It has no significant effect unless it is enabled by
hacking on a variable using a debugger. Hardclock and statclock interrupts
would work even better for this, at least on i386's, provided their
interrupt handlers are fast (as they are in -current but not in -stable
or in my version of -current).
allows us to properly parse cards with attribute memory based CIS that
before wouldn't parse correctly, sometimes with a panic. This allows
me to get my 3C562 modem/ethernet card to fail to attach due to
problems in the ep and sio drivers rather than due to problems in the
CIS parsing code :-).
We weren't setting the address to jump to for the function entries.
This caused us to only work when the addional entries were after the
first ones. On the 3C562/3C563 card this was not the case.
We were also mapping Attribute memory when common memory was asked for
in the target of the LONGLINK_{A,C} or LONGLINK_MFC.
My IBM Home And Away Modem/LAN card still fails for reasons unknown.
This completes the ATA RAID support, since all functions to manipulate
the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards
are only nessesary for booting.
I decided to allow for creation of ATA RAID's on any ATA controller, but
please keep in mind the restrictions on that. Due to the BIOS not
knowing what to do you can only boot from a RAID1 or the first disk
in a SPAN, if its not located on a "real" ATA RAID controller like
the Promise or Highpoint controllers.

The conclusion is that this method really can tell the perfect from the
less than perfect ACPI counters.
It is in fact probably a bit more discriminative than that, but we
will rather condemn some otherwise perfect counters to the slightly
slower "-safe" version, than certify a counter as perfect which
will let us down later.
Many thanks to all the people who sent email reports!
by the hardware are still marked as owned. Handle this by installing a
timeout handler to collect this descriptor to avoid having received
packets remain unhandled until the next one arrives.
- remove some useless code from the status change handler that was intended
to enable the the MII drivers for external phys; this is already done
during interface initialization, and the deleted code made some
assumptions about phy addresses that do not seem to hold true on newer
cards. This should get at least one of the two hmes of newer Netra t1
machines working.
- correct the interrupt resource allocation
- bump the number of RX descriptors, lower values cause promblems on some
machines
not removing tabs before "__P((", and not outdenting continuation lines
to preserve non-KNF lining up of code with parentheses. Switch to KNF
formatting and/or rewrap the whole prototype in some cases.

3c996B-T, with the 5701 rev B5 ASIC). One thing that confuses me
still is that the 'link state change' bit in the status block seems
to change state an awful lot. I have a workaround for this in place
now, but it needs more investigation. For the moment though, this
is enough to get the driver to work with this card.
soon because it's just getting harder and harder to find switches
that correctly implement the GET ALL NEXT subcommands for the SNS
protocol.
Latch up result out pointer and set a busy flag when we're looking
at the response queue. This allows for a cleaner way to make sure
we don't get multiple CPUs trying to read the same response queue
entries.
Change how isp_handle_other_response returns values (clarity).
Make PORT UNAVAILABLE the same as PORT LOGOUT (force a LIP).
Do some formatting changes.
