* 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.

It looks like this was mixed up with the AR9285 calibration code.

Reported by: Path Mather <paul at gromit dot dlib dot vt dot edu>1
Approved by: re (kib)
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.

and dangerous. It will become even more dangerous
when we allow a thread in panic(9) to penetrate all

I understand that the only purpose of this option was
