with IEEE, so use the "real" OUIs for definitions.
Now unfortunately vendors differ in how the MII ID register bits are
used wrt bit and byte ordering. There is a straightforward way - bits
numbered from LSB to MSB - used by AMD, Intel, NS and QS. This is used
by the current MII_OUI() conversion macro. ICS, Seeq, SiS and TI count
the bits as they appear on the wire, and some differ completely.
Account for these cases by "xx" prefixed OUI definitions which compensate
for this, so the MII_OUI() macro can still be used.
Add AMD (the "real" AMD this time) and the 79c973 PCnet internal PHY.

Unfortunately, this must still be deferred to autoconfiguration time,
but there's not much we can do about that right now.
By code inspection I found 2 bugs in the ATAPI code, one may be the cause
of your problem: A counter is not reset when issuing the request_sense
command. This is c_skip, the counter used to track the offset in the data
buffer when a data tranfer needs multiple phases. The effect of this is that
the sense data transfered may be stored outside the sense buffer (sense buffer
+ some, potentially several KB, offset). This can only occur in PIO mode,
DMA is not affected.
This doesn't occur in "normal" use because when reading a data CD, either
the sense is issued for a non-data command (in which case c_skip stays to
0), or an error occured and no data has been transfered, and c_skip is still 0.
I can't see a case where a data READ/WRITE could cause a sense tranfer without
error.
The second problem is that b_resid can be set to a false value (resulting of
the sense tranfer and not the data transfer). Again this is not a problem with
usual data tranfers because both values ends up being 0 when no error occurs.
return 0 instead of EINVAL. In this case, there will only be one media
type, and the upper-level if_media code will ensure that the user is setting
to that type.
In other words, don't require the front-end to provide the no-op.
- Initialize more of the Bt463's registers, instead of leaving them
in undefined states. Notably, the window type table is set up
with 8-plane pseudocolor and 24-plane truecolor modes.
- Bus-space-ify, mostly. Could use some more cleanup, but not until
the rest of the tga stuff is converted, too.
- Do the TGA/RAMDAC communication dance more carefully.

EIO. The spec says ATAPI devices should support "PIO 3 or better".
They are supposed to support less as well. Setting the device to a highter
mode than the controller shoul'nt be a problem, and this is likely what
happens with legaty ISA controllers.

Big-endian CPUs should use bus_space_{read,write}_multi_stream methods
to PIO packet data to NIC in 16-bit or 32-bit chunks.
Make it so.
Since we don't have stream methods on all ports yet (esp. i386), use
the bus_space_{read,write}_multi methods if the compile-time
stream-method feature-test macro is not set.

- Don't rely on ATA signature: some ide controllers seems to not transmit it
properly (SIMIDE on arm32 machines). Instead, when we guess a drive is here
after reset, just mark it as ATA and OLD is it's not ATAPI.
- at attach time, use IDENTIFY to eliminate ghost from the probe. If the
drive had the old flag and IDENTIFY failed, issue a WDCC_RECAL command
to detect a pre-ATA disk. If IDENTIFY succeded, remove the OLD flag,
it's obviously not a pre-ATA disk.
- add a new controller flag, WDC_CAPABILITY_PREATA, used to shorcut parts
of the probe (not necessary, but makes the probe/attach faster). This is
only set by the ISA front-end, all other controllers supported can't have
pre-ATA drives attached.
The mechanism used are more or less the same as before, they have just been
reordered. Should solve port-arm32/7324 (waiting for feedback).
- the cap field is a u_int8_t, so none of the defined flags would fit in.
Looks like nobody had a drive using 16 bytes commands.
- the ACAP_DRQ_* flags are all wrong. Just remove them and use the definitions
from ata/atareg.h, there's no need to duplicate theses. The effect of this
was that we were always polling for the command phase, even for drives
with interrupt DRQ. This didn't break until the code was changed to support
shared interrupts.

* Rearrange the speed mapping table and adjust the code so that the highest

* Do not attach an OPL on the SB1. Writing to the OPL registers at

(XXX Should we access it at 388 instead? The Creative web site claims
that this board *does* have an OPL2, but I haven't played with this
extensively.)
* Allocate the SB DMA channels at open time, rather than attach time, so
that a single DRQ can be used for multiple cards (if only one is in use
at a given time).
(XXX Let me tell you why this is a horrible hack. If the ISA DMA code
tries to allocate a bounce buffer after boot time, it will generally fail,
because there is no contiguous memory below 16MB and the code to allocate
contiguous pages doesn't know how to move things around. Now, we
shouldn't ever be using bounce buffers here, because we use
isa_dmamem_alloc(). So we just turn off BUS_DMA_ALLOCNOW and we don't
actually try to. That's cool, and it even works, but isa_dmamem_alloc()
has the same problem. It just happens that we allocate the ring buffers
at boot time, and whenever we reallocate them (due to the buffer size
changing), we just deallocated the previous (contiguous) buffer, so we get
lucky. This is absolutely disgusting and needs to be fixed.)
