347 | * Modulation for Atheros' eXtended Range - range enhancing extension that is | |
348 | * supposed to double the distance an Atheros client device can keep a | |
349 | * connection with an Atheros access point. This is achieved by increasing | |
350 | * the receiver sensitivity up to, -105dBm, which is about 20dB above what | |
351 | * the 802.11 specifications demand. In addition, new (proprietary) data rates | |
352 | * are introduced: 3, 2, 1, 0.5 and 0.25 MBit/s. | |
353 | * | |
354 | * Please note that can you either use XR or TURBO but you cannot use both, | |
355 | * they are exclusive. | |

360 | * Modulation for Atheros' Turbo G and Turbo A, its supposed to provide a | |
361 | * throughput transmission speed up to 40Mbit/s-60Mbit/s at a 108Mbit/s | |
362 | * signaling rate achieved through the bonding of two 54Mbit/s 802.11g | |
363 | * channels. To use this feature your Access Point must also suport it. | |
364 | * There is also a distinction between "static" and "dynamic" turbo modes: | |
365 | * | |
366 | * - Static: is the dumb version: devices set to this mode stick to it until | |
367 | * the mode is turned off. | |
368 | * - Dynamic: is the intelligent version, the network decides itself if it | |
369 | * is ok to use turbo. As soon as traffic is detected on adjacent channels | |
370 | * (which would get used in turbo mode), or when a non-turbo station joins | |
371 | * the network, turbo mode won't be used until the situation changes again. | |
372 | * Dynamic mode is achieved by Atheros' Adaptive Radio (AR) feature which | |
373 | * monitors the used radio band in order to decide whether turbo mode may | |
374 | * be used or not. | |
375 | * | |
376 | * This article claims Super G sticks to bonding of channels 5 and 6 for | |
377 | * USA: | |
378 | * | |
379 | * http://www.pcworld.com/article/id,113428-page,1/article.html | |
380 | * | |
381 | * The channel bonding seems to be driver specific though. In addition to | |
382 | * deciding what channels will be used, these "Turbo" modes are accomplished | |
383 | * by also enabling the following features: | |
384 | * | |
385 | * - Bursting: allows multiple frames to be sent at once, rather than pausing | |
386 | * after each frame. Bursting is a standards-compliant feature that can be | |
387 | * used with any Access Point. | |
388 | * - Fast frames: increases the amount of information that can be sent per | |
389 | * frame, also resulting in a reduction of transmission overhead. It is a | |
390 | * proprietary feature that needs to be supported by the Access Point. | |
391 | * - Compression: data frames are compressed in real time using a Lempel Ziv | |
392 | * algorithm. This is done transparently. Once this feature is enabled, | |
393 | * compression and decompression takes place inside the chipset, without | |
394 | * putting additional load on the host CPU. | |
395 | * | |

818 | * | |
819 | * @AR5K_INT_RX: mask to identify received frame interrupts, of type | |
820 | * AR5K_ISR_RXOK or AR5K_ISR_RXERR | |
821 | * @AR5K_INT_RXDESC: Request RX descriptor/Read RX descriptor (?) | |
822 | * @AR5K_INT_RXNOFRM: No frame received (?) | |
823 | * @AR5K_INT_RXEOL: received End Of List for VEOL (Virtual End Of List). The | |
824 | * Queue Control Unit (QCU) signals an EOL interrupt only if a descriptor's | |
825 | * LinkPtr is NULL. For more details, refer to: | |
826 | * http://www.freepatentsonline.com/20030225739.html | |
827 | * @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors). | |
828 | * Note that Rx overrun is not always fatal, on some chips we can continue | |
829 | * operation without reseting the card, that's why int_fatal is not | |
830 | * common for all chips. | |
831 | * @AR5K_INT_TX: mask to identify received frame interrupts, of type | |
832 | * AR5K_ISR_TXOK or AR5K_ISR_TXERR | |
833 | * @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?) | |
834 | * @AR5K_INT_TXURN: received when we should increase the TX trigger threshold | |
835 | * We currently do increments on interrupt by | |
836 | * (AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2 | |
837 | * @AR5K_INT_MIB: Indicates the Management Information Base counters should be | |
838 | * checked. We should do this with ath5k_hw_update_mib_counters() but | |
839 | * it seems we should also then do some noise immunity work. | |
840 | * @AR5K_INT_RXPHY: RX PHY Error | |
841 | * @AR5K_INT_RXKCM: ?? | |
842 | * @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a | |
843 | * beacon that must be handled in software. The alternative is if you | |
844 | * have VEOL support, in that case you let the hardware deal with things. | |
845 | * @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing | |
846 | * beacons from the AP have associated with, we should probably try to | |
847 | * reassociate. When in IBSS mode this might mean we have not received | |
848 | * any beacons from any local stations. Note that every station in an | |
849 | * IBSS schedules to send beacons at the Target Beacon Transmission Time | |
850 | * (TBTT) with a random backoff. | |
851 | * @AR5K_INT_BNR: Beacon Not Ready interrupt - ?? | |
852 | * @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now | |
853 | * until properly handled | |
854 | * @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA | |
855 | * errors. These types of errors we can enable seem to be of type | |
856 | * AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR. | |
857 | * @AR5K_INT_GLOBAL: Seems to be used to clear and set the IER | |
858 | * @AR5K_INT_NOCARD: signals the card has been removed | |
859 | * @AR5K_INT_COMMON: common interrupts shared amogst MACs with the same | |
860 | * bit value | |
861 | * | |
862 | * These are mapped to take advantage of some common bits | |
863 | * between the MACs, to be able to set intr properties | |
864 | * easier. Some of them are not used yet inside hw.c. Most map | |
865 | * to the respective hw interrupt value as they are common amogst different | |
866 | * MACs. | |
