2020-08-27mac80211: rename csa counters to countdown countersJohn Crispin1-1/+1
We want to reuse the functions and structs for other counters such as BSS color change. Rename them to more generic names. Signed-off-by: John Crispin <john@phrozen.org> Link: https://lore.kernel.org/r/20200811080107.3615705-2-john@phrozen.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2017-09-25ath9k: remove cast to void pointerHimanshu Jha1-1/+1
casting to void pointer from any pointer type and vice-versa is done implicitly and therefore casting is not needed in such a case. Done using Coccinellle.

2016-07-08ath9k: Remove some #defined constants to decrease verbosityBenjamin Berg1-1/+1
The removed ATH9K_SLOT_TIME_X constants simply map the value in microseconds to the same integer. These constants were not used consistently, so fix the inconsistency issue by replacing all occurances with the integer equivalent.

2012-11-09mac80211: clarify interface iteration and make it configurableJohannes Berg1-3/+3
During hardware restart, all interfaces are iterated even though they haven't been re-added to the driver, document this behaviour. The same also happens during resume, which is even more confusing since all of the interfaces were previously removed from the driver. Make this optional so drivers relying on the current behaviour can still use it, but to let drivers that don't want this behaviour disable it. Also convert all API users, keeping the old semantics except in hwsim, where the new normal ones are desired. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Remove the control.sta pointer from ieee80211_tx_info to free up sufficient space in the TX skb control buffer for the upcoming Transmit Power Control (TPC).

2011-06-01ath9k: Remove ATH9K_BEACON_PERIOD maskRajkumar Manoharan1-4/+4
Earlier beacon_interval is used to hold interval value and some flags (ATH9K_BEACON_ENA &ATH9K_BEACON_PERIOD). So to extract interval ATH9K_BEACON_PERIOD is used. Those flags were completely removed. So masking beacon_interval is not required. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-04-13ath9k_htc: Add TX slotsSujith Manoharan1-4/+13
Maintain a bitmap of slots for transmission and update the cookie field for every packet with the slot value. This value would be used for matching packets when TX completion processing is added.

2011-04-13ath9k_htc: Introduce new HTC APISujith Manoharan1-1/+2
A new routine that takes an endpoint explicitly is introduced. The normal htc_send() now retrieves the endpoint from the packet's private data. This would be useful in TX completion when the endpoint ID would be required. While at it, use a helper function to map the queue to endpoint. Data/mgmt/beacon packets use htc_send(), while WMI comamnds pass the endpoint to HTC. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Fix TX queue managementSujith Manoharan1-0/+4
Handle queue start/stop properly by maintaining a counter to check if the pending frame count has exceeded the threshold. Otherwise, packets would be dropped needlessly. While at it, use a simple flag to track queue status and use helper functions too. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Use SKB's private area for TX parametersSujith Manoharan1-4/+7
For all packets sent through the USB_WLAN_TX_PIPE endpoint, the private area of the SKB's tx_info can be used to store driver-specific information. For packets sent through USB_REG_OUT_PIPE, this will not make a difference since they are routed through a separate routine that doesn't access the private region. This would help in situations where TX information is required in the URB callback. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Queue WMI eventsSujith Manoharan1-16/+11
Use a queue to handle WMI events and schedule a tasklet to process the events. This fixes the race between the WMI event ISR and the SWBA tasklet when the arrival of WMI events in quick succession could overwrite the SWBA data before the tasklet from a previous iteration could have been scheduled. Also, drain the WMI queue properly. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Fix beacon miss under heavy loadSujith Manoharan1-5/+34
Transmission of beacons becomes erratic when TX load is high, since the latency involved in the generation of a SWBA interrupt on the target to the actual sending of a beacon is quite high for USB devices. Fix this by adjusting the beacon response time. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-04-13ath9k_htc: Add TSF adjust capabilitySujith Manoharan1-0/+36

2011-03-30ath9k: fix beacon timer handling issuesFelix Fietkau1-6/+3
AP mode beacon timers in ath9k are configured in milliseconds, which breaks when increasing ATH_BCBUF to 8 instead of 4 (due to rounding errors). Since the hardware timers are actually configured in microseconds, it's better to let the driver use that unit directly. To be able to do that, the beacon interval parameter abuse for passing certain flags needs to be removed. This is easy to do, because those flags are completely unnecessary anyway. ATH9K_BEACON_ENA is ignored, ATH9K_BEACON_RESET_TSF can be replaced with calling ath9k_hw_reset_tsf from the driver directly. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-03-01ath9k_htc: Handle BSSID/AID for multiple interfacesSujith Manoharan1-6/+52
The AID and BSSID should be set in the HW only for the first station interface or adhoc interface. Also, cancel the ANI timer in stop() for multi-STA scenario.

Linville <linville@tuxdriver.com>
2011-02-23ath9k_htc: Fix TBTT calculation for IBSS modeSujith Manoharan1-4/+15
The target beacon transmission time has to be synced with the HW TSF when configuring beacon timers in Adhoc mode. Failing to do this would cause erroneous beacon transmission, for example, on completion of a scan run to check for IBSS merges.

2011-02-23ath9k_htc: Remove OP_ASSOCIATED variableSujith Manoharan1-0/+19
mac80211 stores the association state in ieee80211_bss_conf. Use this and remove the local state, which is incorrect anyway since it is stored globally and not on a per-VIF basis. Restarting ANI and reconfiguration of HW beacon timers when a scan run ends requires more work. This is handled by iterating over the active interfaces. Finally, remove the useless check for associated status in RX processing. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-05-07ath9k_htc: Fix beaconing in IBSS modeSujith1-29/+10
The current way of managing beaconing in ad-hoc mode has a subtle race - the beacon obtained from mac80211 is freed in the SWBA handler rather than the TX completion routine. But transmission of beacons goes through the normal SKB queue maintained in hif_usb, leading to a situation where __skb_dequeue() in the TX completion handler goes kaput. Fix this by simply getting a beacon from mac80211 for every SWBA and free it in its completion routine. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W.
