* add new channels to the end of the list so channels used in order of
addition
* de-globalise definition of struct snddev_info and provide accessor
functions where necessary.
* move the $FreeBSD$ tag in each .c file into a macro and allow the
/dev/sndstat handler to display these when set to maximum verbosity to aid
debugging.
* allow each device to register its own sndstat handler to reduce the amount
of groping sndstat must do in foreign structs.
It appears that a number of PrismII card vendors seem to be doing the
same thing (that is, using the same PCI bridge chip) to support PCI,
but each with their own vendor/product ID. So rather than cut-n-paste
another if statement into the probe routine, it's probably better to
provide support for a table. Adding new devices will be a lot easier
that way.
Add tagged queueing support for new IBM drives.
Add support for Yet Another Promise ATA 100 chip.
Flush disk cache on close.
Dont flush the disk cache on BIO_ORDERED anymore.
Cleanup the tests for DMA on ATAPI devices.
Allow to share ALL irq's even the std irg 14 & 15.
Fix calculation bug in end of media code on CD's.
Add REZERO on opening a CDR/CDRW.
Cleanup ataioctl a bit.
that do not have valid NVRAM. In particular, we were leaving
a retry count set (to retry selection timeouts) when thats
not really what we want. Do some constant string additions
so that LOGDEBUG0 info is useful across all cards.

should be initialized to 0 for PCI adapters which was a side-effect of
the memset in ahc_alloc(). EISA/VL adapters require our unpause value to
include the "levelness" of our interrupt.
This change allows EISA adapters to work again.

prevent/workaround TX lockups in this driver. The secret seems to be to
not let the TX DMA queue become too full. If we have too many packets
in the queue, we should wait for them to drain a bit before trying to
queue more. This should prevent the lockup from occurring, and if it
does occur, there is special code in sf_start() to kick the NIC in the
head and get it going again.
Special thanks to Glen Neff for helping me test this fix.
to properly clear the interrupt register on the no error case. Also,
set the mcr register to zero when we find we can't support the chip.
This fixes the hang on sio driver attach problem in the new pci pccard
code that some people have reported. At least on my machine. I'd
like to get this into 4.4.

probably harmless in this case, since the latter is called on tty
input, which is usually a result of some system call, so we've got
plenty of stack left. It's still nice to fix these things, though, in
case somebody ever decides this driver is a good example of something
(perhaps "what you probably shouldn't do").
night of testing before merging to -stable.
Also added to code to detect TX underruns and automatically increase the
TX threshold to avoid them. Carefully placed diagnostig printf() about
this under #ifdef DIAGNOSTIC to avoid getting any panicky e-mails from
confused users, like I always do with the xl and dc drivers.
common_attach is wrong as common attach initialize some fileds used by
mediainit routine. This was hard to notify because loading driver as kld
lead to mediainit routine being called after common_attach, though probe_phy
is called before.

- Callers of asleep() and await() have been converted to calling tsleep().
The only caller outside of M_ASLEEP was the ata driver, which called both
asleep() and await() with spl-raised, so there was no need for the
asleep() and await() pair. M_ASLEEP was unused.

bypass some extra anti-foot-shooting measures. Currently, its only
effect is to allow detaching a device while it's still open (e.g.,
mounted). This is useful for testing how the system reacts to a disk
suddenly going away, which can happen with some removeable media.
At this point, the force option is only checked on detach, so it
would've been possible to allow the option to be passed with the
MDIOCDETACH operation. This was not done to allow the possibility of
having the force flag influence other tests in the future, which may
not necessarily deal with detaching the device.

native or linux interface, though no apps exist (yet) that can take
advantage of native calling.
