Bruno Randolf b47f407bef ath5k: move rx and tx status structures out of hardware descriptor 
move ath5k_tx_status and ath5k_rx_status structures out of the hardware
descriptor since they are not accessed by the hardware at all. they just
contain converted information from the hardware descriptor. since they are only
used in the rx and tx tasklets there is also no use to keep them for each
descriptor.

* 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.
*

* @rate_code: hardware rate value, used in &struct ath5k_desc, on RX on
* &struct ath5k_rx_status.rs_rate and on TX on
* &struct ath5k_tx_status.ts_rate. Seems the ar5xxx harware supports
* up to 32 rates, indexed by 1-32. This means we really only need
* 6 bits for the rate_code.
* @dot11_rate: respective IEEE-802.11 rate value
* @control_rate: index of rate assumed to be used to send control frames.
* This can be used to set override the value on the rate duration
* registers. This is only useful if we can override in the harware at
* what rate we want to send control frames at. Note that IEEE-802.11
* 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
* ah_proc_rx_desc() the respective hardware rate value is set in
* &struct ath5k_rx_status.rs_rate. On TX the desired rate is set in
* &struct ath5k_tx_status.ts_rate which is later used to setup the
* &struct ath5k_desc correctly. This is the hardware rate map we are

* @AR5K_INT_RXDESC: Request RX descriptor/Read RX descriptor (?)
* @AR5K_INT_RXNOFRM: No frame received (?)
* @AR5K_INT_RXEOL: 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_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
* to the respective hw interrupt value as they are common amogst different
* MACs.
