Additional changes are needed before forced dismounts will work.

16K to 32K and the default fragment size from 2K to 4K.
The rational is that most disks are now running with 4K
sectors. While they can (slowly) simulate 512-byte sectors
by doing a read-modify-write, it is desirable to avoid this
functionality. By raising the minimum filesystem allocation
to 4K, the filesystem will never trigger the small sector
emulation.
Also, the growth of disk sizes has lead us to double the
default block size about every ten years. The rise from 8K
to 16K blocks was done in 2001. So, by the 10-year metric,
the time has come for 32K blocks.

MCR register on the Sunix Sun1699 chip tends to be set but doesn't
seem to have a function. That is, FreeBSD just works (provided the
correct RCLK is used) regardless.

AR9287 EEPROM layout.
The AR9287 only supports 2ghz, so I've removed the 5ghz code (but left
the 5ghz edge flags in there for now) and hard-coded the 2ghz-only
path.
Whilst I'm there, fix a typo (ar9285->ar9287.)
This meets basic TX throughput testing - iperf TX tests == 27-28mbit in 11g,
matching the rest of my 11g kit.
I'm assuming for now that the AR9287 is only open-loop TX power control
(as mine is) so I've hard-coded the attach path to fail if the NIC is
not open-loop.
This greatly simplifies the TX calibration path and the amount of code
which needs to be ported over.
This still isn't complete - the rate calculation code still needs to be
ported and it all needs to be glued together.

without waiting for device readiness (or at least not updating FIS receive
area in time). To workaround that, special quirk was added earlier to wait
for the FIS receive area update. But it was found that under same PCI ID
0x91231b4b and revision 0x11 there are two completely different chip
versions (firmware?): HBA and RAID. The problem is that RAID version in
some cases, such as hot-plug, does not update FIS receive area at all!
To workaround that, differentiate the chip versions by their capabilities,
and, if RAID version found, skip FIS receive area update waiting and read
device signature from the PxSIG register instead. This method doesn't work
for HBA version when PMP attached, so keep using previous workaround there.
It isn't linked into the build because it's missing the TX power
and PDADC programming code.
This code is mostly based on the ath9k codebase, compared against
the Atheros codebase as appropriate.
What's implemented:
* probe/attach
* EEPROM board value programming
* RX initial calibration
* radio channel programming
* general MAC / baseband setup
* async fifo setup
* open-loop tx power calibration
What's missing before it can be enabled by default:
* TX power / calibration setting code
* closed-loop tx power calibration routines
* TSF2 handling
* generic timer support from ath9k

This makes it compatible with the old NFS client for this case.

(SEMB) is unable to communicate to Storage Enclosure Processor (SEP), in
response to hard and soft resets it should among other things return value
0x7F in Status register. The weird side is that it means DRQ bit set, which
tells that reset request is not completed. It would be fine if SEMB was the
only device on port. But if SEMB connected to PMP or built into it, it may
block access to other devices sharing same SATA port.
Make some tunings/fixes to soft-reset handling to workaround the issue:
- ahci(4): request CLO on the port after soft reset to ignore DRQ bit;
- siis(4): gracefully reinitialize port after soft reset timeout (hardware
doesn't detect reset request completion in this case);
- mvs(4): if PMP is used, send dummy soft-reset to the PMP port to make it
clear DRQ bit for us.
For now this makes quirks in ata_pmp.c, hiding SEMB ports of SiI3726/SiI4726
PMPs, less important. Further, if hardware permit, I hope to implement real
SEMB support.

values for the commands, compared to the internal command values
(HAL_ANI_CMD.)
My eventual aim is to make the HAL_ANI_CMD internal enum match
the public API and then remove all this messiness.
This now allows HAL_CAP_INTMIT users to use a public HAL_CAP_INTMIT_
enum rather than magic constants.
The only magic constants currently used by if_ath are "enable" and
"present". Some local tools of mine allow for direct, manual fiddling
of the ANI variables and I'll convert these to use the public enum API
before I commit them.

* Change HAL_ANI_* commands _back_ to be numerical, rather than a
bitmap;
* modify access to the ANI control bitmap to convert a command to
a bitmap;
* Fix the ANI noise immunity fiddling for CCK errors - it wasn't
checking whether noise immunity was disabled or not.
