Overhaul regulatory support: o remove HAL_CHANNEL; convert the hal to use net80211 channels; this mostly involves mechanical changes to variable names and channel attribute macros o gut HAL_CHANNEL_PRIVATE as most of the contents are now redundant with the net80211 channel available o change api for ath_hal_init_channels: no more reglass id's, no more outdoor indication (was a noop), anM contents o add ath_hal_getchannels to have the hal construct a channel list without altering runtime state; this is used to retrieve the calibration list for the device in ath_getradiocaps o add ath_hal_set_channels to take a channel list and regulatory data from above and construct internal state to match (maps frequencies for 900MHz cards, setup for CTL lookups, etc) o compact the private channel table: we keep one private channel per frequency instead of one per HAL_CHANNEL; this gives a big space savings and potentially improves ani and calibration by sharing state (to be seen; didn't see anything in testing); a new config option AH_MAXCHAN controls the table size (default to 96 which was chosen to be ~3x the largest expected size) o shrink ani state and change to mirror private channel table (one entry per frequency indexed by ic_devdata) o move ani state flags to private channel state o remove country codes; use net80211 definitions instead o remove GSM regulatory support; it's no longer needed now that we pass in channel lists from above o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A o simplify initial channel list construction based on the EEPROM contents; we preserve country code support for now but may want to just fallback to a WWR sku and dispatch the discovered country code up to user space so the channel list can be constructed using the master regdomain tables o defer to net80211 for max antenna gain o eliminate sorting of internal channel table; now that we use ic_devdata as an index, table lookups are O(1) o remove internal copy of the country code; the public one is sufficient o remove AH_SUPPORT_11D conditional compilation; we always support 11d o remove ath_hal_ispublicsafetysku; not needed any more o remove ath_hal_isgsmsku; no more GSM stuff o move Conformance Test Limit (CTL) state from private channel to a lookup using per-band pointers cached in the private state block o remove regulatory class id support; was unused and belongs in net80211 o fix channel list construction to set IEEE80211_CHAN_NOADHOC, IEEE80211_CHAN_NOHOSTAP, and IEEE80211_CHAN_4MSXMIT o remove private channel flags CHANNEL_DFS and CHANNEL_4MS_LIMIT; these are now set in the constructed net80211 channel o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one of the driver-private flag bits of the net80211 channel o move 900MHz frequency mapping into the hal; the mapped frequency is stored in the private channel and used throughout the hal (no more mapping in the driver and/or net80211) o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the calculation and available in the net80211 channel o change noise floor calibration logic to work with compacted private channel table setup; this may require revisiting as we no longer can distinguish channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used only to calculate status data we can live with it for now o change ah_getChipPowerLimits internal method to operate on a single channel instead of all channels in the private channel table o add ath_hal_gethwchannel to map a net80211 channel to a h/w frequency (always the same except for 900MHz channels) o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory problems o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now o change ath_hal_getwirelessmodes to really return wireless modes supported by the hardware (was previously applying regulatory constraints) o return channel interference status with IEEE80211_CHANSTATE_CWINT (should change to a callback so hal api's can take const pointers) o remove some #define's no longer needed with the inclusion of <net80211/_ieee80211.h> Sponsored by: Carlson Wireless

Add a new HAL method to retrieve the completion schedule. It sets the completion schedule from the hardware and returns AH_TRUE if the hardware supports multi-rate retries (AR5212 and above); and returns AH_FALSE if the hardware doesn't support multi-rate retries. The sample rate module directly reads the TX completion descriptor and extracts the TX schedule information from that. It will be updated in a future commit to instead use this method to determine the completion schedule.

ANI changes #1 - split out the ANI polling from the RxMonitor hook. The rxmonitor hook is called on each received packet. This can get very, very busy as the tx/rx/chanbusy registers are thus read each time a packet is received. Instead, shuffle out the true per-packet processing which is needed and move the rest of the ANI processing into a periodic event which runs every 100ms by default.

Begin adding support to explicitly set the current chainmask. Right now the only way to set the chainmask is to set the hardware configured chainmask through capabilities. This is fine for forcing the chainmask to be something other than what the hardware is capable of (eg to reduce TX/RX to one connected antenna) but it does change what the HAL hardware chainmask configuration is. For operational mode changes, it (may?) make sense to separately control the TX/RX chainmask. Right now it's done as part of ar5416_reset.c - ar5416UpdateChainMasks() calculates which TX/RX chainmasks to enable based on the operating mode. (1 for legacy and whatever is supported for 11n operation.) But doing this in the HAL is suboptimal - the driver needs to know the currently configured chainmask in order to correctly enable things for each TX descriptor. This is currently done by overriding the chainmask config in the ar5416 TX routines but this has to disappear - the AR9300 HAL support requires the driver to dynamically set the TX chainmask based on the TX power and TX rate in order to meet mini-PCIe slot power requirements. So: * Introduce a new HAL method to set the operational chainmask variables; * Introduce null methods for the previous generation chipsets; * Add new driver state to record the current chainmask separate from the hardware configured chainmask. Part #2 of this will involve disabling ar5416UpdateChainMasks() and moving it into the driver; as well as properly programming the TX chainmask based on the currently configured HAL chainmask. Tested: * AR5416, STA mode - both legacy (11a/11bg) and 11n rates - verified that AR_SELFGEN_MASK (the chainmask used for self-generated frames like ACKs and RTSes) is correct, as well as the TX descriptor contents is correct.

Add some missing DFS chipset functionality to the FreeBSD HAL.

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.)

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.

The ANI control for the AR5416 and later chips was calling ar5212AniControl(), 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.

Include the initial support for external EEPROMs. The AR9100 at least doesn't have an external serial EEPROM attached to the MAC; it instead stores the calibration data in the normal system flash. I believe earlier parts can do something similar but I haven't experienced it first-hand. This commit introduces an eepromdata pointer into the API but doesn't at all commit to using it. A future commit will include the glue needed to allow the AR9100 support code to use this data pointer as the EEPROM.

Add initial support for the AR9485 CUS198 / CUS230 variants. These variants have a few differences from the default AR9485 NIC, namely: * a non-default antenna switch config; * slightly different RX gain table setup; * an external XLNA hooked up to a GPIO pin; * (and not yet done) RSSI threshold differences when doing slow diversity. To make this possible: * Add the PCI device list from Linux ath9k, complete with vendor and sub-vendor IDs for various things to be enabled; * .. and until FreeBSD learns about a PCI device list like this, write a search function inspired by the USB device enumeration code; * add HAL_OPS_CONFIG to the HAL attach methods; the HAL can use this to initialise its local driver parameters upon attach; * copy these parameters over in the AR9300 HAL; * don't default to override the antenna switch - only do it for the chips that require it; * I brought over ar9300_attenuation_apply() from ath9k which is cleaner and easier to read for this particular NIC. This is a work in progress. I'm worried that there's some post-AR9380 NIC out there which doesn't work without the antenna override set as I currently haven't implemented bluetooth coexistence for the AR9380 and later HAL. But I'd rather have this code in the tree and fix it up before 11.0-RELEASE happens versus having a set of newer NICs in laptops be effectively RX deaf. Tested: * AR9380 (STA) * AR9485 CUS198 (STA) Obtained from: Qualcomm Atheros, Linux ath9k

There's apparently a bug with Merlin (AR9280) and later chipsets where putting descriptors (not buffers) across a 4k page boundary can cause issues. I've not seen it in production myself but it apparently can cause problems. So, in preparation for addressing this workaround, (re)-expose the particular HAL capability bit which marks whether the chipset has support for cross-4k- boundary transactions or not. A subsequent commit will modify the descriptor allocation to avoid allocating descriptor entries that straddle a 4k page boundary.

Add a HAL capability bit for supporting self-linked RX descriptors and disable it for the 11n chipsets. From the ath9k source: == 11N: we can no longer afford to self link the last descriptor. MAC acknowledges BA status as long as it copies frames to host buffer (or rx fifo). This can incorrectly acknowledge packets to a sender if last desc is self-linked. == Since this is useful for pre-AR5416 chips that communicate PHY errors via error frames rather than by on-chip counters, leave the support in there, but disable it for AR5416 and later.
