Fix for the Intel WiFi Link 1000. The EEPROM image is in the OTPROM block
before the last block, not in the last block itself.

Change the way shutdown is handled for log file.
pmc_flush_logfile is now non-blocking and just ask the kernel
to shutdown the file. From that point, no more data is
accepted by the log thread and when the last buffer is flushed
the file is closed.
This will remove a deadlock between pmcstat asking for
flush while it cannot flush the pipe itself.
Remove programming LED register and enable 25MHz TX clock for
88E1149 PHY. This will fix intermittent watchdog timeouts as well
as very slow network performance on 88E8072 Yukon Extreme.

Implement LCD brightness control notify handler.

Make sanity check slightly more useful and tweak an error message.

Add support for `cycle' and `zero' events for LCD brightness control.

Rename some macros to clarify their intentions and fix style nits.
Several changes to fix livelock under high load, introduced by r203489:
- change the way in which command queue overflow is handled;
- do not expose to CAM two command slots, used for driver's internal purposes;
- allow driver to use up to 1024 command slots, instead of 256 before.
framebuffer driver, etc. work on FreeBSD/amd64.
A significant amount of improvements were done by jkim@ during the recent
months to make vesa(4) work better, over the initial code import. This
work is based on OpenBSD's x86emu implementation and contributed by
paradox <ddkprog yahoo com> and swell.k at gmail com.
Hopefully I have stolen all their work to 8-STABLE :)
All bugs in this commit are mine, as usual.
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.
