later.
* Don't set HAL_PHYERR_PARAM_ENABLE in pe_relstep to say whether
radar detection is on.
* Return whether blockradar, fir128 and enmaxrssi is enabled.
* Change some of the phyerr params to be integers rather than
HAL_BOOL so they can be set to the NOPARAM value when the
setup function is called. This is in line with other radar
parameters.
* Add new configuration parameters for fir128, blockradar and
enmaxrssi, rather than defaulting to off, on and on respectively.

These should be disabled for the AR5416 in hostap/mesh/ibss mode,
as the AR5416 doesn't have support for radar detection on the
ext channel of a HT40 setup. Later chips do.

to do about the few cases where the HAL state isn't available (regdomain)
or isn't yet setup (probe/attach.)
The global ath_hal_debug now affects all instances of the HAL.
This also restores the ability for probe/attach debugging to work; as
the sysctl tree may not be attached at that point. Users can just set
the global "hw.ath.hal.debug" to a suitable value to enable probe/attach
related debugging.
rather than global variables.
This specifically allows for debugging to be enabled per-NIC, rather
than globally.
Since the ath driver doesn't know about AH_DEBUG, and to keep the ABI
consistent regardless of whether AH_DEBUG is enabled or not, enable the
debug parameter always but only conditionally compile in the debug
methods if needed.
The ALQ support is currently still global pending some brainstorming.

For the AR5211/AR5212, this is apparently a one byte pulse duration
counter value. It is only coded up here for the AR5212 as I don't have
any AR5211-series hardware to test it on.
This information was extracted from the Madwifi DFS branch along with
some local additions.
Please note - all this does is extract out the radar event duration,
it in no way reflects the presence of a radar. Further code is needed
to take a set of radar events and filter them to extract out correct
radar pulse trains (and ignore other events.)

Please note - this doesn't in any way constitute a full DFS
implementation, it merely adds the relevant capability bits and
radar detection threshold register access.
The particulars:
* Add new capability bits outlining what the DFS capabilities
are of the various chipsets.
* Add HAL methods to set and get the radar related register values.
* Add AR5212 and AR5416+ DFS radar related register value
routines.
* Add a missing HAL phy error code that's related to radar event
processing.
* Add HAL_PHYERR_PARAM, a data type that encapsulates the radar
register values.
The AR5212 routines are just for completeness. The AR5416 routines
are a super-set of those; I may later on do a drive-by pass to
tidy up duplicate code.

support it, and since now the HAL has functional AR9287+11n support,

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.

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.

which did AR5212 specific initialisation. This would cause some slight
silliness when enabling/disabling ANI.
Just to be completely correct - and to ensure the phy error mask/RX filter
register isn't incorrectly played with - make the ANI control function a
method, have it set appropriately for AR5212/AR5416, and call that from the
ANI control interface.
This should hopefully make it clearer to developers what is going on
and when TPC is being hacked on, make it obvious why it isn't working for
series 1, 2, 3.
I won't flip on setting TX power for TX series 1, 2, 3 until I've done
some further testing with Kite to ensure it doesn't break anything.
(Before people ask - yes, TPC is only needed for 5ghz regdomains and
yes, Kite is a 2.4ghz only chip, but there are potential use cases
for 2ghz TPC. I just need to sit down and ensure it's supported and
functional.)
control the antenna control bits for the four TX series and the
TPC settings for TX series 1, 2, 3.
The specifics:
* The TPC setting for TX series 0 is handled in ctl0.
* TPC is currently disabled, so the per-packet TX power is
set via the global per-rate TX power register, not per packet.
* The antenna control bits don't matter for AR5416 and later
so they should stay 0 (which they currently do); they may
be set for Kite but as there's no TX diversity supported
at the moment (it requires the NIC to be built with an
external antenna switch, matching how antenna diversity
is done on legacy NICs), so again keep them 0.
This is in preparation for supporting per-rate TPC on the
AR5416 and later. The Kite (and soon to come Kiwi) code
sets ctl8-11 to 0x0, which doesn't have any effect at
the moment. When TPC is enabled it would result in the
second, third and fourth TX series attmpts to be done with
a TX power of 0. This commit doesn't change that; it'll
be followed up with some commits to properly set the TPC
registers appropriately.
the multicast key search support for AR5212, AR5416 and later.
The general HAL routine ath_hal_getcapability() implement checking this
but it's overridden by a check in ar5212_misc:ar5212GetCapability().
This restores the later functionality in case it's found to be broken
in any of the 11n chipsets.
Since the returned NF will be -ve, checking for <= 0 is not good
enough. For now, check whether it equals 0 or -1; a future commit
will tidy this mess up and have it return HAL_BOOL instead.
The eeprom Get method should return HAL_OK if fastclock is enabled in the
EEPROM. It was returning the opposite of what it should have.

The code assumed it could return HAL_OK, HAL_EINVAL and other
HAL_STATUS types; so it shouldn't be declared as returning HAL_BOOL.

I've tested this locally and it does indeed read and attach to an AR9287
EEPROM. But a lot more code needs to be ported over to the HAL before
the AR9287 is functional.
I'm importing this separate from the rest of the codebase (and unlinked from
the build for now) in case someone wishes to begin fiddling with porting
the rest of the code over from Linux ath9k.

The Atheros HAL code does this for Sowl/Howl but not for Owl (AR5416) where
