---help---
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.

* Modulation for Atheros' eXtended Range - range enhancing extension that is
* supposed to double the distance an Atheros client device can keep a
* connection with an Atheros 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.
*
*/
#define MODULATION_XR 0x00000200
/*
* Modulation for Atheros' Turbo G and Turbo A, its 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 your Access Point must also suport 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:
*
* http://www.pcworld.com/article/id,113428-page,1/article.html
*
* The channel bonding seems to be driver specific though. In addition to
* deciding what channels will be used, these "Turbo" modes are accomplished
* by also enabling the following features:
*
* - 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.

* This can be used to set override the value on the rate duration

* Ch. 9.6 (after IEEE 802.11g changes) defines the rate at which we
* should send ACK/CTS, if we change this value we can be breaking
* the spec.
*
* This structure is used to get the RX rate or set the TX rate on the
* hardware descriptors. It is also used for internal modulation control
* and settings.
*
* On RX after the &struct ath5k_desc is parsed by the appropriate

* @AR5K_INT_RXNOFRM: No frame received (?)
* @AR5K_INT_RXEOL: received End Of List for VEOL (Virtual End Of List). The

* LinkPtr is NULL. For more details, refer to:
* http://www.freepatentsonline.com/20030225739.html
* @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors).
* Note that Rx overrun is not always fatal, on some chips we can continue
* operation without reseting the card, that's why int_fatal is not
* common for all chips.
* @AR5K_INT_TX: mask to identify received frame interrupts, of type
* AR5K_ISR_TXOK or AR5K_ISR_TXERR
* @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?)
* @AR5K_INT_TXURN: received when we should increase the TX trigger threshold
* We currently do increments on interrupt by
* (AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2
* @AR5K_INT_MIB: Indicates the Management Information Base counters should be
* checked. We should do this with ath5k_hw_update_mib_counters() but
* it seems we should also then do some noise immunity work.
* @AR5K_INT_RXPHY: RX PHY Error
* @AR5K_INT_RXKCM: ??
* @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_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 Not Ready interrupt - ??
* @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now
* until properly handled
* @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA
* errors. These types of errors we can enable seem to be of type
* AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR.
* @AR5K_INT_GLOBAL: Seems to be used to clear and set the IER
* @AR5K_INT_NOCARD: signals the card has been removed
* @AR5K_INT_COMMON: common interrupts shared amogst 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

/*
* RF Buffer register
*
* There are some special control registers on the RF chip
* that hold 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 buffer register and
* then write on another special register to notify hw
* to apply the settings. This is done so that control registers
* can be dynamicaly programmed during operation and the settings
* are applied faster on the hw.
*
* We sent such data packets during rf initialization and channel change
* through ath5k_hw_rf*_rfregs and ath5k_hw_rf*_channel functions.
*
* The data packets we send during initializadion are inside ath5k_ini_rf
* struct (see ath5k_hw.h) and each one is related to an "rf register bank".
* We use *rfregs functions to modify them acording to current operation
* mode and eeprom values and pass them all together to the chip.
*
* It's obvious from the code that 0x989c is the buffer register but
* for the other special registers that we write to after sending each
* packet, i have no idea. So i'll name them BUFFER_CONTROL_X registers
* for now. It's interesting that they are also used for some other operations.
*
* Also check out hw.h and U.S. Patent 6677779 B1 (about buffer
* registers and control registers):
