The AR9280 apparently has an issue with descriptors which straddle a page
boundary (4k). I'm not yet sure whether I should use PAGE_SIZE in the
calculations or whether I should use 4096; the reference code uses 4096.
This patch fiddles with descriptor allocation so a descriptor entry
doesn't straddle a 4kb address boundary. The descriptor memory allocation
is made larger to contain extra descriptors and then the descriptor
address is advanced to the next 4kb boundary where needed.
I've tested this both on Merlin (AR9280) and non-Merlin (in this case,
AR9160.)

These wording changes clarify the default rollover behavior
as a "kludge". Also, the block numbers and octet counts for 65535 blocks
and 32767 blocks are more accurate than the existing documented numbers.

the block counter would rollover to 0 if a file larger
than 65535 blocks was transferred. With the default block size
of 512 octets per block, this is a file size of approximately 32 megabytes.
The new TFTP server code would report an error and stop transferring
the file if a file was larger than 65535 blocks.
This patch restores the old TFTP server's behavior to the new
TFTP server code. If a TFTP client transfers a file larger
than 65535 blocks, and does *not* specify the "rollover" option,
then automatically rollover the block counter to 0 every time
we reach 65535 blocks.
This restores interoperability with the FreeBSD 6 TFTP client.
Without this change, if a FreeBSD 6 TFTP client tried to
retrieve a file larger than 65535 blocks from a FreeBSD 9 TFTP server
, the transfer would fail.
The same file could be retrieved successfully if the same FreeBSD 6
TFTP client was used against a FreeBSD 6 TFTP server.

This is a followup to r222032 and a reimplementation of it.
While that revision fixed the race for the smp_rv_waiters[2] exit
sentinel, it still left a possibility for a target CPU to access
stale or wrong smp_rv_func_arg in smp_rv_teardown_func.
To fix this race the slave CPUs signal when they are really fully
done with the rendezvous and the master CPU waits until all slaves
are done.

This seems to indicate whether to program the NIC for fractional 5ghz
mode (ie, 5mhz spaced channels, rather than 10 or 20mhz spacing) or not.
The default (0) seems to mean "only program fractional mode if needed".
A different value (eg 1) seems to always enable fractional 5ghz mode
regardless of the frequency.

Calibration/PCI data that's written to flash (rather than EEPROM attached
to the NIC) is typically already in host-endian. The existing checks
end up swapping 16 bit words incorrectly - the correct solution would be
to read the magic value and determine the EEPROM endianness from that.
(This is what Linux does.)
This doesn't completely enable embedded use of the AR9285/AR9287 -
notably, the EEPROM read methods need to be made generic and available
to all EEPROM drivers. I'll worry about that later.

* Teach the AR5212/AR5416 ANI code to use the RX filter methods, rather
than calling the RX filter routines directly.
* Make HAL_ANI_PRESENT and HAL_ANI_MODE unconditionally available,
regardless of whether ah_ani_function is masking it.
* (Mostly) fully disable ANI if interference mitigation is disabled.
When disabled, the ANI code doesn't touch any ANI/PHY registers,
leaving them the default value. This is in line with what the
Atheros reference driver does.
* Correctly set the ANI parameters during ANI reset, rather than
when ANI is enabled. In this way, if ANI is disabled or enabled
whilst the NIC is not active (and there's no current channel),
bogus parameters or a NULL pointer deference doesn't occur.
There's still some lingering issues - notably, the MIB events/interrupts
aren't fully disabled, so MIB interrupts still occur. I'll worry about
that later.

This in particular fixes radar PHY handling - on the AR5212
NIC, one enables the AR_PHY_ERR_RADAR bit in AR_PHY_ERR;
the AR5416 and later also needs a bit set in AR_RX_FILTER.
A follow-up commit is needed to convert the AR5416 ANI code
to use this particular method, as it's currently using the
AR5212 methods directly.

I've been told that the dual-ADC is only engaged in turbo/40mhz modes.
Since Sowl (AR9160) seems to return valid-looking calibration data
in 5ghz 20MHz modes, I'm only disabling it for Merlin for now.
It may turn out I can disable it for all chipsets and only enable
it for 40MHz modes.

Although this may not be what the original sysctl was designed to do,
it feels a bit more "expected".
Before, if ANI is disabled, the initial ANI parameters are still written
to the hardware, even if they're not enabled. "ANI enabled" would then
adjust the noise immunity parameters dynamically. Disabling ANI would
simply leave the existing noise immunity parameters where they are,
and disable the dynamic part.
The problem is that disabling ANI doesn't leave the hardware in
a consistent, predictable state - so asking a user to disable ANI
wouldn't actually reset the NIC to a consistent set of PHY signal
detection parameters, resulting in an unpredictable/unreliable outcome.
This makes it difficult to get reliable debugging information from
the user.

Slot field of the PxCMD register may point to an empty command slot.
That breaks command timeout detection logic, making impossible to find
what command actually caused timeout, and leading to infinite wait.
Workaround that by checking whether pointed command slot is really used
and can timeout in its time. And if not, fallback to the dumb algorithm
used with FBS -- let all commands to time out and then fail all of them.

respond to any commands. I've found that because of multiple command
retries, each of which cause 30s timeout, bus reset and another retry or
requeue for many commands, it may take ages to eventually drop the
failed device. The odd thing is that those retries continue even after
XPT considered device as dead and invalidated it.
This patch makes cam_periph_error() to block any command retries after
periph was marked as invalid. With that patch all activity completes in
1-2 minutes, just after several timeouts, required to consider device
death. This should make ZFS, gmirror, graid, etc. operation more robust.
