On legacy channels every once in a while the firmware throws a SYSASSERT
on line 208. On HT channels though this does always happen and I'm not
aware of any workaround currently.
was not updated to pass CRD_F_KEY_EXPLICIT flag to opencrypto. This resulted in
always using first key.
We need to support providers created with this bug, so set special
G_ELI_FLAG_FIRST_KEY flag for GELI provider in integrity mode with version
smaller than 6 and pass the CRD_F_KEY_EXPLICIT flag to opencrypto only if
G_ELI_FLAG_FIRST_KEY doesn't exist.

It isn't used yet; ar5416GetWirelessModes() needs to be taught
about this rather than assuming HT20/HT40 is available.
This seems to make the AR9160 behave better during heavy scanning,
where before it'd hang and require a hard reset to recover.

There's a hardware workaround which sets disabling some errors
early at startup and clears said bits before the PCU begins
receiving - it does this to avoid RX descriptor status errors.
It's possible these bits aren't being completely properly twiddled
in all instances; but in particular if the diag_reg HAL variable
is set it won't be setting these bits correctly. I'll review this
at some point.
* Disable multicast search on mac address and key id - the driver
doesn't use it at the moment and thus adhoc may be broken for
merlin and later.
* Change this to be for Merlin 1.0 (which from what I understand
wasn't ever publicly released) to be more correct.
Apparently all three RX chains need to be enabled before initial calibration
is done, even if only two are configured.
Reorder the alt chain swap bit to match what the Atheros HAL is doing.

* Shuffle some of the capability numbers around to match the
Atheros HAL capability IDs, just for consistency.
* Add some new capabilities to FreeBSD from the Atheros
HAL which will be be shortly used when new chipsets are added
(HAL SGI-20 support is for Kiwi/AR9287 support); for
TX aggregation (MBSSID aggregate support, WDS aggregation
support); CST/GTT support for carrier sense/TX timeout.
channel when the channel is HT/40.
The new ANI code (primarily for the AR9300/AR9400) in ath9k sets this
register but the ANI code for the previous 11n chips didn't set this.
Unlike ath9k, only set this for HT/40 channels.

These describe FCC/Japan channel and DFS behaviour.
The AR9285 and later chips don't set these bits in the eeprom, the correct
behaviour is to just assume all five bits are enabled.
An optical disk may not have a TOC (e.g. for blank media) and userland
software may legitimately try to use CDIOREADTOCHEADER to find out about
the TOC.

The Atheros HAL and FreeBSD HAL share the same capabilities up
until HAL_CAP_11D, where things begin to diverge.
I'll look at tidying these up soon.

* Add Howl (ar9130) to the list of chips that have DFS/BB/MAC hangs
* Don't treat unknown BB hangs as fatal; ath9k/Atheros HAL don't
treat it as such.
* Add HAL_DEBUG_DFS to the debug fields in ath_hal/ah_debug.h
The BB hang check simply loops over an observation register checking
for a stuck state engine, but it can happen under high traffic
conditions. Ath9k and the Atheros HAL simply log a debug message and
continue.
Private to FreeBSD:
* Add HAL_DEBUG_HANG to the debug fields
* Change the hang debugging to HAL_DEBUG_HANG rather than HAL_DEBUG_DFS
like in the Atheros HAL.

For now, these are equivalent macros. AR_SREV_OWL{X}_OR_LATER
will later change to exclude Howl (AR9130) in line with what
the Atheros HAL does.
This should not functionally change anything.

A quick story, which is partially documented in the commit.
The silicon revision in Linux ath9k and the Atheros HAL use an
AR_SREV_REVISION mask of 0x07.
FreeBSD's HAL uses the AR5212 AR_SREV_REVISION mask of 0x0F.
Thus the OWL silicon revisions were coming through as 0xA, 0xB,
0xC, rather than 0x0, 0x1 and 0x2.
My ath9k-sourced AR_SREV_OWL_<X> macros were thus using the wrong
silicon revision values and wouldn't correctly match.
This commit does a few things:
* Change the AR_SREV_OWL_<x> macros to use the AR_SREV_REVISION_OWL_*
values, not AR_XSREV_REVISION_OWL macros;
* Disable AR_XSREV_REVISION_OWL_* values;
* Modify the IS_5416 to properly check the MAC is OWL, rather than
potentially matching on non-OWL revisions (which shouldn't happen
unless there's a silicon revision of higher than 0x9 in a later
chip..)
* Add a couple more macros from the Atheros HAL for compatibility.
The main difference now is that the Atheros HAL defines
AR_SREV_OWL_{20,22}_OR_LATER subtly differently - it fails on all HOWL
silicon. The AR_SREV_5416_*_OR_LATER macros match on the relevant OWL
version -and- all HOWL versions, along with subsequent versions.
A subsequent commit is going to migrate the uses of AR_SREV_OWL_X_OR_LATER
to AR_SREV_5416_X_OR_LATER to match what's going on in the Atheros HAL.
There's only two uses of AR_SREV_OWL_X_OR_LATER which currently don't
apply to FreeBSD but it may do in the future.
Yes, it's all confusing!
