MFC r228817:
Use the correct types when calling the decompression mask function.
There's currently no public code which uses this feature and the current reference driver doesn't enable this feature at all. It's possible it was used by a previous version of the driver and that indeed it should return HAL_STATUS; but at this point I'm happy to require that they complain and submit a patch.
This was found by LLVM compile-time type checking.

Update the TSF and next-TBTT methods to work for the AR5416 and later NICs. This is another commit in a series of TDMA support fixes for the 11n NICs.
* Move ath_hal_getnexttbtt() into the HAL; write methods for it. This returns a timer value in TSF, rather than TU.
* Move ath_hal_getcca() and ath_hal_setcca() into the HAL too, where they likely now belong.
* Create a new HAL capability: HAL_CAP_LONG_RXDESC_TSF. The pre-11n NICs write 15 bit TSF snapshots into the RX descriptor; the AR5416 and later write 32 bit TSF snapshots into the RX descriptor. * Use the new capability to choose between 15 and 31 bit TSF adjustment functions in ath_extend_tsf().
* Write ar5416GetTsf64() and ar5416SetTsf64() methods. ar5416GetTsf64() tries to compensate for TSF changes at the 32 bit boundary.
According to yin, this fixes the TDMA beaconing on 11n chipsets and TDMA stations can now associate/talk, but there are still issues with traffic stability which need to be investigated.
The ath_hal_extendtsf() function is also used in RX packet timestamping; this may improve adhoc mode on the 11n chipsets. It also will affect the timestamps seen in radiotap frames.

Add another HAL method - ah_isFastClockEnabled - which returns AH_TRUE if 5ghz fast clock is enabled in the current operating mode.
It's slightly dirty, but it's part of the reference HAL and used by the (currently closed-source) radar event code to map radar pulses back to microsecond durations.

Fix AR5416 radar parameter initialisation.

Modify the radar API a little to be easier to "change" via run-time tools.
* introduce pe_enabled, which (will) indicate whether the radar detection stuff is enabled or not. Right now it's incorrectly set, based on something previously written. I'll sort it out 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.

Break out most of the HAL related tweaks into a per-HAL instance, 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.

Flesh out a new HAL method to fetch the radar PHY error frame information.
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.)
For further information, please see:
http://wiki.freebsd.org/dev/ath_hal%284%29/RadarDetection

Add some missing DFS chipset functionality to the FreeBSD HAL.
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.

When disabling RIFS for Sowl (AR9160) and Howl (AR9130), make sure RIFS is totally disabled.
The Atheros HAL code does this for Sowl/Howl but not for Owl (AR5416) where RIFS is disabled by default.
This seems to quieten the occasional baseband hang I've been seeing with the AR9160 in STA mode under constant heavy traffic load.

Do a HAL capabilities sync pass based on the Atheros HAL.
* 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.

Some BB hang changes:
* 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.

Introduce AR9130 (HOWL) WMAC support to the FreeBSD HAL.
The AR9130 is an AR9160/AR5416 family WMAC which is glued directly to the AR913x SoC peripheral bus (APB) rather than via a PCI/PCIe bridge.
The specifics:
* A new build option is required to use the AR9130 - AH_SUPPORT_AR9130. This is needed due to the different location the RTC registers live with this chip; hopefully this will be undone in the future. This does currently mean that enabling this option will break non-AR9130 builds, so don't enable it unless you're specifically building an image for the AR913x SoC.
* Add the new probe, attach, EEPROM and PLL methods specific to Howl.
* Add a work-around to ah_eeprom_v14.c which disables some of the checks for endian-ness and magic in the EEPROM image if an eepromdata block is provided. This'll be fixed at a later stage by porting the ath9k probe code and making sure it doesn't break in other setups (which my previous attempt at this did.)
* Sprinkle Howl modifications throughput the interrupt path - it doesn't implement the SYNC interrupt registers, so ignore those.
* Sprinkle Howl chip powerup/down throughout the reset path; the RTC methods were
* Sprinkle some other Howl workarounds in the reset path.
* Hard-code an alternative setup for the AR_CFG register for Howl, that sets up things suitable for Big-Endian MIPS (which is the only platform this chip is glued to.)
This has been tested on the AR913x based TP-Link WR-1043nd mode, in legacy, HT/20 and HT/40 modes.
Caveats:
* 2ghz has only been tested. I've not seen any 5ghz radios glued to this chipset so I can't test it.
* AR5416_INTERRUPT_MITIGATION is not supported on the AR9130. At least, it isn't implemented in ath9k. Please don't enable this.
* This hasn't been tested in MBSS mode or in RX/TX block-aggregation mode.

Antenna diversity on the >= AR5416 is implemented differently than the AR5212 and previous chips. So for now, and not to confuse things, just disable it for now.

Replace most compile-time support options with linker sets for chip and RF backend support: o add OS_DATA_SET and OS_SET_DECLARE os requirements for setting up linker sets o add AH_CHIP macro for registering chip support (e.g. 5210) o add AH_RF macro for registering RF support (e.g. 2413); note this isn't required for single chip solutions where there's no ambiguity (e.g. 5416/9160+2133) but for 5212 class parts it's required because of the multi-chip solutions o remove all uses of AH_SUPPORT_AR5210, AH_SUPPORT_AR5211, AH_SUPPORT_5212, and AH_SUPPORT_AR9160; still need AH_SUPPORT_AR5416 to enable the 11n descriptor formats and 5312 support is presently broken o remove all uses of AH_SUPPORT_2133, AH_SUPPORT_2413, AH_SUPPORT_5111, AH_SUPPORT_5112, AH_SUPPORT_2417, AH_SUPPORT_2425, and AH_SUPPORT_5413; 5312-related support still requires fixup
Remaining issues: o fixup SoC attach o ath_hal_attach uses a hack to probe w/o access to the vendorid o fallback handling of parts w/o a macrev needs to be restored
