GPIB overhaul, part #2: make the tnt4882 driver work with the newer
TNT5004 IC. This involved a major rewrite of a number of things, as
this chip no longer supports the NAT7210 legacy mode but requires the
host to use the (more modern) FIFO mode.
In theory, this also ought to work on the older TNT4882C chip. I'll
probably add this as optional support (perhaps by a device.hints flag)
later on. By now, FIFO mode is *only* activates iff a TNT5004 chip
has been detected (where the old code didn't work at all), while
everything else is supposed to use the old code.
Increase Max Read Request Size for PCIe chips from 512 to 1024 bytes.
It gives those beasts additional 10% of write bandwidth.
Use new helper functions to do it.
With FBS enabled, we have no idea what command caused timeout.
Implement same logic as in siis(4) - wait for other commands
complete or timeout and then give some more time.
Document the usfs driver and the NO_SYSCTL_DESCR option, and update the comment
for umass.
Don't include the sysctl description variables in aic7xxx when NO_SYSCTL_DESCR
is used.

Add FIS-based switching support. If controller supports FBS, it allows
several devices beyond Port Multiplier to work simultaneously, substantially
increasing performance.
- Give ATA/SATA SIMs info about ATAPI packet size, supported by device.
- Make ATA XPT to reject longer SCSI CDBs then supported by device, or
any SCSI CDBs, if device doesn't support ATAPI.
Large set of CAM improvements:
- Unify bus reset/probe sequence. Whenever bus attached at boot or later,
CAM will automatically reset and scan it. It allows to remove duplicate
code from many drivers.
- Any bus, attached before CAM completed it's boot-time initialization,
will equally join to the process, delaying boot if needed.
- New kern.cam.boot_delay loader tunable should help controllers that
are still unable to register their buses in time (such as slow USB/
PCCard/ CardBus devices), by adding one more event to wait on boot.
- To allow synchronization between different CAM levels, concept of
requests priorities was extended. Priorities now split between several
"run levels". Device can be freezed at specified level, allowing higher
priority requests to pass. For example, no payload requests allowed,
until PMP driver enable port. ATA XPT negotiate transfer parameters,
periph driver configure caching and so on.
- Frozen requests are no more counted by request allocation scheduler.
It fixes deadlocks, when frozen low priority payload requests occupying
slots, required by higher levels to manage theit execution.
- Two last changes were holding proper ATA reinitialization and error
recovery implementation. Now it is done: SATA controllers and Port
Multipliers now implement automatic hot-plug and should correctly
recover from timeouts and bus resets.
- Improve SCSI error recovery for devices on buses without automatic sense
reporting, such as ATAPI or USB. For example, it allows CAM to wait, while
CD drive loads disk, instead of immediately return error status.
- Decapitalize diagnostic messages and make them more readable and sensible.
- Teach PMP driver to limit maximum speed on fan-out ports.
- Make boot wait for PMP scan completes, and make rescan more reliable.
- Fix pass driver, to return CCB to user level in case of error.
- Increase number of retries in cd driver, as device may return several UAs.
Add support for SATA part of Marvell 88SE912x controllers to ahci(4).
Limit early revisions from 6Gb/s to 3Gb/s by default, or they negotiate
only 1.5Gb/s, when 3Gb/s devices connected.
Add dummy driver for PATA part of these controllers, preventing generic
driver attach them. It causes system freeze when SATA controller used after
PATA was touched.
Make ata_getrev() an optional method by implementing ata_null_getrev().
This fixes a bogus '???' boot message on Cambria boards with a CompactFlash
card.
Make OSS_GETVERSION ioctl really work. It has 'M' group, not 'P',
as different nearby ones, and was grabbed by MIXER_xxx() handler.
While there, replace '(cmd & MIXER_xxx(0)) == MIXER_xxx(0)' expressions
with more correct '(cmd & ~0xff) == MIXER_xxx(0)'. Use of bit operations
to compare numeric fields doesn't looks sane.
Don't panic on failure to attach if we fail before or during the
if_alloc() of ifp.
This fixes the panic reported in the PRs, but not the attach failure.

Rename aac_fast_intr to aac_filter to reflect its current use. Eliminate
the fallback of using the filter as an interrupt handler, as it is no
longer needed.

- Improve tracer, to handle more cases of input-to-output monitoring
loopback.
- Use "igain" mixer control for input-to-output monitoring loopback.
- Allow AD1981HD codecs to use playback mixer. Now driver should be able to
really use it.
- Fix bug in shared muters operation.
(S)LIST_HEAD_INITIALIZER takes a (S)LIST_HEAD as an argument.

Overhaul of the pcii driver:
. Properly allocate all IO space resources. These cards scatter their
IO addresses over a range of 0x1600 bytes, and they require an
additional address for "special interrupt handling".
. Implement the "special interrupt handling" per the GPIB-PCIIA
Technical Reference Manual; this was apparently not declared for the
clone card this driver has been originally implemented for, but it
turned out to be needed for both, an original NI brand PCII/PCIIA
card as well as the Axiom AX5488 clone.
. Add some diagnostic messages for various resource allocation etc.
failures during probe.
. Add some comments about the structure of the IO address space that
is used by these cards.
Fix a handful of issues with via agp support.
* Read the pci capability register to identify AGP 3 support
* Add missing smaller aperture sizes for AGP3 chips.
* Fix the aperture size calculation on AGP2 chips.
All sizes between 32M and 256M reported as 256M.
* Add \n to error string.
o Add PCI ID for BCM 5756.
o Don't enable BGE_FLAG_BER_BUG on both 5722 and 5756, and based
on their PCI IDs rather than their chip IDs.
