The PIOBM is used by only one driver (will be added later,
stay tuned) and intruduce an attribute "ata_piobm" so that
it will be conditionally compiled in.
The "ata_dma" (busmastering transfer using ATA DMA mode) and
"ata_udma" (busmastering transfer using ATA Ultra DMA mode)
attributes are also added for consistency, but unused for now.

bits(3).
Make the __BIT and __BITS macros "widthless," as best I can, by

dev/ic/wd33c93.c. This may not be the best WD33C93 driver we've
got, but it's the most recently worked on and probably the most
portable, so it seems like a good basis for further work (and in
particular an acorn26 driver for the Acorn SCSI card). There's
no functional change in this commit, and sgimips kernels still
compile.

in the bus layer and remove from common ath_attach().
Having it in both layers (on some bus architectures)
was causing a double call to ath_stop() on shutdown
which in turn was tickling the bus lockup described
therin on slower machines.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Keep track of the average RSSI using an Exponential Moving Average (EMA).
Use it to dynamically tune radio receive sensitivity.
The idea is simple:
- increase sensitivity when the RSSI is bad to optimize throughput on
long distance to the AP, and
- decrease sensitivity when the RSSI is good to reduce noise level and
optimize throughput on short distance to the AP
The EMA allows to smooth RSSI variations so we don't end up changing the
sensitivity too frequently. We check if it would be worth updating the
sensitivity every one second.
RSSI thresholds were taken from the Ralink Tech. Linux driver.

New HAL includes some driver changes to register accesses.
Adds support for WLAN devices on AR5312 family devices.
Adds support 32-bit SPARC ath devices (untested).
ath enabled in SPARC64 GENERIC builds.
This HAL is tested and known to work for i386 PCI devices, SPARC64 PCI devices,
and AR5312 WiSoC devices. MIPS PCI devices appear to be busted (possibly only
on Alchemy hardware, unconfirmed), and cardbus support is untested due to
lack of test hardware.
Please report any new problems with this import to garrett@.

Not yet enabled because I don't have a CardBus controller to test and it

After revision 1.135 of scsipi_base.c, it's a big no-no to set
XS_STS_DONE before calling scsipi_done(). Besides, scsipi_done()
sets XS_STS_DONE itself after checking that it's not already set.
This puts this driver back in working order; before this change
the probe of the logical drives would cause a hang.

requested by uwe@. These were wrong because they were receiving an
emulcookie yet they were accessops (thus having to receive an accesscookie).
Instead, just handle the WSDISPLAYIO_{GET,PUT}WSCHAR ioctls from the
driver's ioctl accessop.
As this reduces the amount of code needed to handle these operations to
two small functions in each driver, remove the WSDISPLAY_CHARFUNCS kernel
option.

This flag could be useful if host's BIOS (firmware) initializes
ahc(4) chip with some conservative (async, no tagged queuing etc.)

so that the signal and noise are in dB, not dBm. Since dBm signal

in the wrong order. That made for some astonishing (and wrong)
radiotap captures. dB signal and noise come after the antenna
field, so everything is in the right order, now.
I had duplicated them. Improve the macros' names. Simplify their
implementation.
A brief description of each macro is below.
BIT(n): Return a bitmask with bit m set, where the least
significant bit is bit 0.
BITS(m, n): Return a bitmask with bits m through n, inclusive,
set. It does not matter whether m>n or m<=n.
The least significant bit is bit 0.
A "bitfield" is a span of consecutive bits defined by a
bitmask, where 1s select the bits in the bitfield. SHIFTIN,
SHIFTOUT, and SHIFTOUT_MASK help read and write bitfields
from device registers.
SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
defined by `mask', and return them. No
side-effects.
SHIFTOUT(v, mask): Extract and return the bitfield selected
by `mask' from `v', right-shifting the
bits so that the rightmost selected bit
is at bit 0. No side-effects.
SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
the rightmost non-zero bit is at bit
0. This is useful for finding the
greatest unsigned value that a bitfield
can hold. No side-effects. Note that
SHIFTOUT_MASK(m) = SHIFTOUT(m, m).
