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. + * + */ +#define MODULATION_TURBO 0x00000080 + +enum ath5k_driver_mode { + AR5K_MODE_11A = 0, + AR5K_MODE_11A_TURBO = 1, + AR5K_MODE_11B = 2, + AR5K_MODE_11G = 3, + AR5K_MODE_11G_TURBO = 4, + AR5K_MODE_XR = 0, + AR5K_MODE_MAX = 5 +}; + + +/****************\ + TX DEFINITIONS +\****************/ + +/* + * TX Status descriptor + */ +struct ath5k_tx_status { + u16 ts_seqnum; + u16 ts_tstamp; + u8 ts_status; + u8 ts_rate[4]; + u8 ts_retry[4]; + u8 ts_final_idx; + s8 ts_rssi; + u8 ts_shortretry; + u8 ts_longretry; + u8 ts_virtcol; + u8 ts_antenna; +}; + +#define AR5K_TXSTAT_ALTRATE 0x80 +#define AR5K_TXERR_XRETRY 0x01 +#define AR5K_TXERR_FILT 0x02 +#define AR5K_TXERR_FIFO 0x04 + +/** + * enum ath5k_tx_queue - Queue types used to classify tx queues. + * @AR5K_TX_QUEUE_INACTIVE: q is unused -- see ath5k_hw_release_tx_queue + * @AR5K_TX_QUEUE_DATA: A normal data queue + * @AR5K_TX_QUEUE_XR_DATA: An XR-data queue + * @AR5K_TX_QUEUE_BEACON: The beacon queue + * @AR5K_TX_QUEUE_CAB: The after-beacon queue + * @AR5K_TX_QUEUE_UAPSD: Unscheduled Automatic Power Save Delivery queue + */ +enum ath5k_tx_queue { + AR5K_TX_QUEUE_INACTIVE = 0, + AR5K_TX_QUEUE_DATA, + AR5K_TX_QUEUE_XR_DATA, + AR5K_TX_QUEUE_BEACON, + AR5K_TX_QUEUE_CAB, + AR5K_TX_QUEUE_UAPSD, +}; + +#define AR5K_NUM_TX_QUEUES 10 +#define AR5K_NUM_TX_QUEUES_NOQCU 2 + +/* + * Queue syb-types to classify normal data queues. + * These are the 4 Access Categories as defined in + * WME spec. 0 is the lowest priority and 4 is the + * highest.

This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.

This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed.

Docs say that we must write 0 on this register on AP mode to start TSF increment, we do both to be on the safe side. * Fix num_tx_pending function, we never read the register :P that's why we got all those "beacon queue 7 didn't stop messages". * Put full prioriy on beacon queue, lock all queues with lower priority using the arblock and also bypass any arblock by seting the arblock ignore flag. * For the CAB queue (do we need this thing ?, it seems crap) since it's supposed to fire up after each beacon (we don't use it on driver part, ath9k/MadWiFi does), don't make it DBA gated but instead make it fire after each beacon by using the beacon sent gated flag. * Increase bmiss threshold to 10, that's what we used on MadWiFi for a long time. Also when we have pending frames on the beacon queue (we got a beacon that didn't make it on the air) it's more likely that the beacon queue never started, probably due to faulty DBA setting, so change that "beacon queue didn't stop" message. Tested this with AP mode and IBSS mode and seems to work fine ;-) Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W.

If we manualy set the channel after hostapd starts (by setting channel to 0 -auto), beacons are sent but they wont show up on scan because they are malformed (they have channel = 0 because hostapd doesn't update the channel info -this is probably a hostapd bug so i'm CCing Jouni) and they get dropped. Bob fixed this by only allowing standard channels to be registered so now hostapd works as expected. * Docs (and HAL source) say that we must write 0 on timer0 when operating on AP mode to start TSF increment but this seems to mess with DBA in many cases and beacon queue never gets started. We fixed that on the previous patch. We have some more things to deal with... * For some reason (hw bug or something else) after restarting hostapd a few times, beacon inteval seems to change from 100ms to a sec (we get one beacon per sec). * We need to set sleep timers on STA mode and enable power saving + support PCF. ...but i think it's time we enable AP support "officialy" so that we can get more feedback from users. I ran ath5k with the mentioned patches + hostapd 0.6.8 and AP mode worked fine (it had some less throughput on my tests than IBSS but it worked).
