which is automatically included during kernel config, and add comments
to individual machine-dependant majors.* files to assign new MI majors
in MI file.
Range 0-191 is reserved for machine-specific assignments, range
192+ are MI assignments.

* Implement read for ulpt.
* If the device is not opened for reading, occasionally drain any
data the printer might have (but don't hammer the printer with reads).
* Lower the buffer size to one page.
The driver seems to work with more printers now.
>- Move PMAGB-BA and PMAG-JA (which I have) out of "may be incorrect" entries.
>- Put driver name "tfb" for PMAG-JA (which will appear in future pmax-wscons).
removing assumptions that there are only two B channels and by
adding support for a varying number of channels.
Due to this, rename previously used isdn identified "bri" to "isdnif",
which better describes the current situation.
* auich_calibrate() assumes that the AC97 part is in its reset state. To
ensure this, call audio_attach_mi() after auich_calibrate().
* Explicitly support 12000Hz and 24000Hz. (Why is there a discrete list at
all?)
* Fix an obvious recording bug -- we were acking the wrong interrupt.
* Ensure that we don't get an interrupt during the AC97 speed probe by clearing
the "interrupt on completion" bit in the DMA setup.
* Separate the code to set the default parameters into a new function,
audio_set_defaults(). Make it use audiosetinfo(), which properly initializes
the block size and whatnot. Use this in both audioattach() and the
/dev/audio case of audio_open().
* Do not force a reinitialization when /dev/sound is opened.
* Do all of the block size sanity checks in auto_init_ringbuffer(), not in
both audio_calc_blksize() and audiosetinfo().
* Fix a bug in audiosetinfo() that caused the block size to not be recalculated
immediately if we set it to 0.
* For AUDIO_GET[IO]OFFS, modify the deltablks calculation so that it gives us
the number of block boundaries crossed.

to pci_attach_args. The latter is allocated on the stack during auto-
configuration and so will not be valid after that time.
It's amazing how the old code worked for so long. I guess pci_attach_args
is allocated deep in pid#0's kernel stack on most platforms.
fit in the number of bits used for the port still does something.
This fixes PR pkg/18741 for ac97-based hardware. Other audio drivers
might need a similar fix.
- if_bcereg.h should only have register definitions, so declarations
of softc structure etc. should be in if_bce.c.
- The types of DMA descriptors should be u_int32_t, not unsigned long.
- netinet headers are not required here.
- Values passed via bce_tx_ring should also be byte-swapped.
- byte-swapping is not needed for bus_space access.
from me:
- KNF
- mark all magic numbers with /* MAGIC */ so they can be identified at
some point. there are 33 in total though many appear to be the same
value, or related (eg, the 6 emac points.)
leaves these issues:
- RX pre-packet headers need to be byte-swapped or not?
- PAGE_SIZE bytes are allocated for both TX and RX DMA ring descriptors,
but they should be 1024 (== sizeof(struct bce_dma_slot) * N[TR]XDESC).
- the mcast filter.
it should be there, but in practice, on some systems an ugly race condition
rears its head: SCSI commands are issued before the FC thread ever runs, and
fail from then on forever. Yuck.
