We have access to common->curbssid and common->curaid so just use those. Note that common->curaid is always 0 so this keeps our current behaviour of always using 0 for now. Once we fix storing the association ID passed by mac80211 this will require no changes here. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

#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.

/**
|
|
* enum ath5k_int - Hardware interrupt masks helpers
|
|
*
|
|
* @AR5K_INT_RX: mask to identify received frame interrupts, of type
|
|
* AR5K_ISR_RXOK or AR5K_ISR_RXERR
|
|
* @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: 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_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: 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.
