+	  This module adds support for wireless adapters based on
+	  Atheros 5xxx chipset.
+
+	  Currently the following chip versions are supported:
+
+	  MAC: AR5211 AR5212
+	  PHY: RF5111/2111 RF5112/2112 RF5413/2413
+
+	  This driver uses the kernel's mac80211 subsystem.
+
+	  If you choose to build a module, it'll be called ath5k. Say M if
+	  unsure.
+
+config ATH5K_DEBUG
+	bool "Atheros 5xxx debugging"
+	depends on ATH5K
+	help
+	  Atheros 5xxx debugging messages.
+
+	  Say Y, if and you will get debug options for ath5k.
+	  To use this, you need to mount debugfs:
+
+	  mount -t debugfs debug /sys/kernel/debug
+
+	  You will get access to files under:
+	  /sys/kernel/debug/ath5k/phy0/
+
+	  To enable debug, pass the debug level to the debug module
+	  parameter. For example:
+
+	  modprobe ath5k debug=0x00000400
+
+config ATH5K_TRACER
+	bool "Atheros 5xxx tracer"
+	depends on ATH5K
+	depends on EVENT_TRACING
+	help
+	  Say Y here to enable tracepoints for the ath5k driver
+	  using the kernel tracing infrastructure.  Select this
+	  option if you are interested in debugging the driver.
+
+	  If unsure, say N.
+
+config ATH5K_AHB
+	bool "Atheros 5xxx AHB bus support"
+	depends on ATH25 && ATH5K
+	help
+	  This adds support for WiSoC type chipsets of the 5xxx Atheros
+	  family.

+/**
+ * DOC: Basic ANI Operation
+ *
+ * Adaptive Noise Immunity (ANI) controls five noise immunity parameters
+ * depending on the amount of interference in the environment, increasing
+ * or reducing sensitivity as necessary.
+ *
+ * The parameters are:
+ *
+ *   - "noise immunity"
+ *
+ *   - "spur immunity"
+ *
+ *   - "firstep level"
+ *
+ *   - "OFDM weak signal detection"
+ *
+ *   - "CCK weak signal detection"
+ *
+ * Basically we look at the amount of ODFM and CCK timing errors we get and then
+ * raise or lower immunity accordingly by setting one or more of these
+ * parameters.
+ *
+ * Newer chipsets have PHY error counters in hardware which will generate a MIB
+ * interrupt when they overflow. Older hardware has too enable PHY error frames
+ * by setting a RX flag and then count every single PHY error. When a specified
+ * threshold of errors has been reached we will raise immunity.
+ * Also we regularly check the amount of errors and lower or raise immunity as
+ * necessary.

+ *
+ * Atheros' eXtended Range - range enhancing extension is a modulation scheme
+ * that is supposed to double the link distance between an Atheros XR-enabled
+ * client device with an Atheros XR-enabled access point. This is achieved
+ * by increasing the receiver sensitivity up to, -105dBm, which is about 20dB
+ * above what the 802.11 specifications demand. In addition, new (proprietary)
+ * data rates are introduced: 3, 2, 1, 0.5 and 0.25 MBit/s.
+ *
+ * Please note that can you either use XR or TURBO but you cannot use both,
+ * they are exclusive.
+ *
+ * Also note that we do not plan to support XR mode at least for now. You can
+ * get a mode similar to XR by using 5MHz bwmode.
+ */
+
+
+/**
+ * DOC: Atheros SuperAG
+ *
+ * In addition to XR we have another modulation scheme called TURBO mode
+ * that is supposed to provide a throughput transmission speed up to 40Mbit/s
+ * -60Mbit/s at a 108Mbit/s signaling rate achieved through the bonding of two
+ * 54Mbit/s 802.11g channels. To use this feature both ends must support it.
+ * There is also a distinction between "static" and "dynamic" turbo modes:
+ *
+ * - Static: is the dumb version: devices set to this mode stick to it until
+ *     the mode is turned off.
+ *
+ * - Dynamic: is the intelligent version, the network decides itself if it
+ *     is ok to use turbo. As soon as traffic is detected on adjacent channels
+ *     (which would get used in turbo mode), or when a non-turbo station joins
+ *     the network, turbo mode won't be used until the situation changes again.
+ *     Dynamic mode is achieved by Atheros' Adaptive Radio (AR) feature which
+ *     monitors the used radio band in order to decide whether turbo mode may
+ *     be used or not.
+ *
+ * This article claims Super G sticks to bonding of channels 5 and 6 for
+ * USA:
+ *
+ * https://www.pcworld.com/article/id,113428-page,1/article.html
+ *
+ * The channel bonding seems to be driver specific though.
+ *
+ * In addition to TURBO modes we also have the following features for even
+ * greater speed-up:
+ *
+ * - Bursting: allows multiple frames to be sent at once, rather than pausing
+ *     after each frame. Bursting is a standards-compliant feature that can be
+ *     used with any Access Point.
+ *
+ * - Fast frames: increases the amount of information that can be sent per
+ *     frame, also resulting in a reduction of transmission overhead. It is a
+ *     proprietary feature that needs to be supported by the Access Point.
+ *
+ * - Compression: data frames are compressed in real time using a Lempel Ziv
+ *     algorithm. This is done transparently. Once this feature is enabled,
+ *     compression and decompression takes place inside the chipset, without
+ *     putting additional load on the host CPU.
+ *
+ * As with XR we also don't plan to support SuperAG features for now. You can
+ * get a mode similar to TURBO by using 40MHz bwmode.

+ * @AR5K_INT_RXEOL: Reached "End Of List", means we need more RX descriptors
+ * @AR5K_INT_RXORN: Indicates we got RX FIFO overrun. Note that Rx overrun is
+ *		not always fatal, on some chips we can continue operation
+ *		without resetting the card, that's why %AR5K_INT_FATAL is not
+ *		common for all chips.
+ * @AR5K_INT_RX_ALL: Mask to identify all RX related interrupts
+ *
+ * @AR5K_INT_TXOK: Frame transmission success
+ * @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor
+ * @AR5K_INT_TXERR: Frame transmission failure
+ * @AR5K_INT_TXEOL: Received End Of List for VEOL (Virtual End Of List). The
+ *		Queue Control Unit (QCU) signals an EOL interrupt only if a
+ *		descriptor's LinkPtr is NULL. For more details, refer to:
+ *		"http://www.freepatentsonline.com/20030225739.html"
+ * @AR5K_INT_TXNOFRM: No frame was transmitted within a specified time period
+ * @AR5K_INT_TXURN: Indicates we got TX FIFO underrun. In such case we should
+ *		increase the TX trigger threshold.
+ * @AR5K_INT_TX_ALL: Mask to identify all TX related interrupts
+ *
+ * @AR5K_INT_MIB: Indicates the either Management Information Base counters or
+ *		one of the PHY error counters reached the maximum value and
+ *		should be read and cleared.
+ * @AR5K_INT_SWI: Software triggered interrupt.
+ * @AR5K_INT_RXPHY: RX PHY Error
+ * @AR5K_INT_RXKCM: RX Key cache miss
+ * @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a
+ *		beacon that must be handled in software. The alternative is if
+ *		you have VEOL support, in that case you let the hardware deal
+ *		with things.
+ * @AR5K_INT_BRSSI: Beacon received with an RSSI value below our threshold
+ * @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing
+ *		beacons from the AP have associated with, we should probably
+ *		try to reassociate. When in IBSS mode this might mean we have
+ *		not received any beacons from any local stations. Note that
+ *		every station in an IBSS schedules to send beacons at the
+ *		Target Beacon Transmission Time (TBTT) with a random backoff.
+ * @AR5K_INT_BNR: Beacon queue got triggered (DMA beacon alert) while empty.
+ * @AR5K_INT_TIM: Beacon with local station's TIM bit set
+ * @AR5K_INT_DTIM: Beacon with DTIM bit and zero DTIM count received
+ * @AR5K_INT_DTIM_SYNC: DTIM sync lost
+ * @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill switches connected to
+ *		our GPIO pins.
+ * @AR5K_INT_BCN_TIMEOUT: Beacon timeout, we waited after TBTT but got noting
+ * @AR5K_INT_CAB_TIMEOUT: We waited for CAB traffic after the beacon but got
+ *		nothing or an incomplete CAB frame sequence.
+ * @AR5K_INT_QCBRORN: A queue got it's CBR counter expired
+ * @AR5K_INT_QCBRURN: A queue got triggered wile empty
+ * @AR5K_INT_QTRIG: A queue got triggered
+ *
+ * @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by bus/DMA
+ *		errors. Indicates we need to reset the card.
+ * @AR5K_INT_GLOBAL: Used to clear and set the IER
+ * @AR5K_INT_NOCARD: Signals the card has been removed
+ * @AR5K_INT_COMMON: Common interrupts shared among MACs with the same
+ *		bit value
+ *
+ * These are mapped to take advantage of some common bits
+ * between the MACs, to be able to set intr properties
+ * easier. Some of them are not used yet inside hw.c. Most map
+ * to the respective hw interrupt value as they are common among different

+ * we can also have descriptors for failed TX/RX tries). We have two kind of
+ * descriptors for RX and TX, control descriptors tell the hw how to send or
+ * receive a packet where to read/write it from/to etc and status descriptors
+ * that contain information about how the packet was sent or received (errors
+ * included).
+ *
+ * Descriptor format is not exactly the same for each MAC chip version so we

+ * - Various statistics
+ *
+ * -Different operating modes: AP, STA, IBSS

+ * This is a workaround for IBSS mode
+ *
+ * The need for this function arises from the fact that we have 4 separate
+ * HW timer registers (TIMER0 - TIMER3), which are closely related to the
+ * next beacon target time (NBTT), and that the HW updates these timers
+ * separately based on the current TSF value. The hardware increments each
+ * timer by the beacon interval, when the local TSF converted to TU is equal
+ * to the value stored in the timer.
+ *
+ * The reception of a beacon with the same BSSID can update the local HW TSF
+ * at any time - this is something we can't avoid. If the TSF jumps to a
+ * time which is later than the time stored in a timer, this timer will not
+ * be updated until the TSF in TU wraps around at 16 bit (the size of the
+ * timers) and reaches the time which is stored in the timer.
+ *
+ * The problem is that these timers are closely related to TIMER0 (NBTT) and
+ * that they define a time "window". When the TSF jumps between two timers
+ * (e.g. ATIM and NBTT), the one in the past will be left behind (not
+ * updated), while the one in the future will be updated every beacon
+ * interval. This causes the window to get larger, until the TSF wraps
+ * around as described above and the timer which was left behind gets
+ * updated again. But - because the beacon interval is usually not an exact
+ * divisor of the size of the timers (16 bit), an unwanted "window" between
+ * these timers has developed!
+ *
+ * This is especially important with the ATIM window, because during
+ * the ATIM window only ATIM frames and no data frames are allowed to be
+ * sent, which creates transmission pauses after each beacon. This symptom
+ * has been described as "ramping ping" because ping times increase linearly
+ * for some time and then drop down again. A wrong window on the DMA beacon
+ * timer has the same effect, so we check for these two conditions.

+ * Noise floor calibration: When we tell the hardware to

+ * sample-and-hold the minimum noise level seen at the antennas.
+ * This value is then stored in a ring buffer of recently measured
+ * noise floor values so we have a moving window of the last few
+ * samples. The median of the values in the history is then loaded
+ * into the hardware for its own use for RSSI and CCA measurements.
+ * This type of calibration doesn't interfere with traffic.
+ *
+ * AGC calibration: When we tell the hardware to perform
+ * an AGC (Automatic Gain Control) calibration by setting the
+ * AR5K_PHY_AGCCTL_CAL, hw disconnects the antennas and does
+ * a calibration on the DC offsets of ADCs. During this period
+ * rx/tx gets disabled so we have to deal with it on the driver
+ * part.
+ *
+ * I/Q calibration: When we tell the hardware to perform
+ * an I/Q calibration, it tries to correct I/Q imbalance and
+ * fix QAM constellation by sampling data from rxed frames.
+ * It doesn't interfere with traffic.
+ *
+ * For more infos on AGC and I/Q calibration check out patent doc

+* Antenna control *
+\*****************/
+
+/**
+ * DOC: Antenna control
+ *
+ * Hw supports up to 14 antennas ! I haven't found any card that implements
+ * that. The maximum number of antennas I've seen is up to 4 (2 for 2GHz and 2
+ * for 5GHz). Antenna 1 (MAIN) should be omnidirectional, 2 (AUX)
+ * omnidirectional or sectorial and antennas 3-14 sectorial (or directional).
+ *
+ * We can have a single antenna for RX and multiple antennas for TX.
+ * RX antenna is our "default" antenna (usually antenna 1) set on
+ * DEFAULT_ANTENNA register and TX antenna is set on each TX control descriptor
+ * (0 for automatic selection, 1 - 14 antenna number).
+ *
+ * We can let hw do all the work doing fast antenna diversity for both
+ * tx and rx or we can do things manually. Here are the options we have
+ * (all are bits of STA_ID1 register):
+ *
+ * AR5K_STA_ID1_DEFAULT_ANTENNA -> When 0 is set as the TX antenna on TX
+ * control descriptor, use the default antenna to transmit or else use the last
+ * antenna on which we received an ACK.
+ *
+ * AR5K_STA_ID1_DESC_ANTENNA -> Update default antenna after each TX frame to
+ * the antenna on which we got the ACK for that frame.
+ *
+ * AR5K_STA_ID1_RTS_DEF_ANTENNA -> Use default antenna for RTS or else use the
+ * one on the TX descriptor.
+ *
+ * AR5K_STA_ID1_SELFGEN_DEF_ANT -> Use default antenna for self generated frames
+ * (ACKs etc), or else use current antenna (the one we just used for TX).
+ *
+ * Using the above we support the following scenarios:
+ *
+ * AR5K_ANTMODE_DEFAULT -> Hw handles antenna diversity etc automatically
+ *
+ * AR5K_ANTMODE_FIXED_A	-> Only antenna A (MAIN) is present
+ *
+ * AR5K_ANTMODE_FIXED_B	-> Only antenna B (AUX) is present
+ *
+ * AR5K_ANTMODE_SINGLE_AP -> Sta locked on a single ap
+ *
+ * AR5K_ANTMODE_SECTOR_AP -> AP with tx antenna set on tx desc
+ *
+ * AR5K_ANTMODE_SECTOR_STA -> STA with tx antenna set on tx desc
+ *
+ * AR5K_ANTMODE_DEBUG Debug mode -A -> Rx, B-> Tx-
+ *
+ * Also note that when setting antenna to F on tx descriptor card inverts
+ * current tx antenna.

+ * DOC: Queue Control Unit (QCU)/DCF Control Unit (DCU) functions
+ *
+ * Here we setup parameters for the 12 available TX queues. Note that
+ * on the various registers we can usually only map the first 10 of them so
+ * basically we have 10 queues to play with. Each queue has a matching
+ * QCU that controls when the queue will get triggered and multiple QCUs
+ * can be mapped to a single DCU that controls the various DFS parameters
+ * for the various queues. In our setup we have a 1:1 mapping between QCUs
+ * and DCUs allowing us to have different DFS settings for each queue.
+ *
+ * When a frame goes into a TX queue, QCU decides when it'll trigger a
+ * transmission based on various criteria (such as how many data we have inside
+ * it's buffer or -if it's a beacon queue- if it's time to fire up the queue
+ * based on TSF etc), DCU adds backoff, IFSes etc and then a scheduler
+ * (arbitrator) decides the priority of each QCU based on it's configuration
+ * (e.g. beacons are always transmitted when they leave DCU bypassing all other
+ * frames from other queues waiting to be transmitted). After a frame leaves
+ * the DCU it goes to PCU for further processing and then to PHY for
+ * the actual transmission.

+ * DOC: RF Buffer registers
+ *
+ * There are some special registers on the RF chip
+ * that control various operation settings related mostly to
+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the chip, using a special register,
+ * that holds all the settings we need. After we've sent the
+ * data packet, we write on another special register to notify hw
+ * to apply the settings. This is done so that control registers
+ * can be dynamically programmed during operation and the settings
+ * are applied faster on the hw.
+ *
+ * We call each data packet an "RF Bank" and all the data we write
+ * (all RF Banks) "RF Buffer". This file holds initial RF Buffer
+ * data for the different RF chips, and various info to match RF
+ * Buffer offsets with specific RF registers so that we can access
+ * them. We tweak these settings on rfregs_init function.
+ *
+ * Also check out reg.h and U.S. Patent 6677779 B1 (about buffer
+ * registers and control registers):
