The MVM_FW_BCAST_FILTER_PASS_ALL option defined in iwl-dbg-cfg.ini configuration file allows to enable/disable FW broadcast filtering. If MVM_FW_BCAST_FILTER_PASS_ALL is not defined in iwl-dbg-cfg.ini or its value is 0, the mvm broadcast filtering is enabled.

Getting the BSS station vif is something that may be needed by other parts of the code. So, instead of having an iterator specifically for d3, change it into a generic one in utils.c.

2014-10-29iwlwifi: mvm: move the check if associated outside of the iterator for wowlanLuciano Coelho
Instead of checking if we are associated when suspending with wowlan enabled in the interface iterator, allow it to return an unassociated vif and move the check to the main suspend function. This will be needed by netdetect, since it should also work when we are not associated but the vif is active.

2014-10-29iwlwifi: mvm: split wowlan handling out of the main suspend functionLuciano Coelho
Take the WoWLAN handling code out of the main suspend function, dividing it into three parts: get_config (which is used before the firmware is switched), switch_to_d3 (which handles the rebooting of the hardware with the D3 firmware) and config (which configures the D3 firmware for WoWLAN operation). This is necessary to prepare for the net-detect implementation, which will use only the switch_to_d3 part of this flow.

2014-10-23iwlwifi: mvm: ROC - bug fixes around time events and lockingMatti Gottlieb
Don't add the time event to the list. We added it several times the same time event, which leads to an infinite loop when walking the list. Since we (currently) don't support more than one ROC for STA vif at a time, enforce this and don't add the time event to any list.

2014-09-21iwlwifi: mvm: rs: fix logic in case of multiple TIDsEyal Shapira
In case of traffic on multiple TIDs where one is aggregated and the other is not RS would toggle between considering traffic vs. the station as aggregated and not aggregated. Instead consider the sta state as aggregated as long as there's at least one TID aggregated. This limitation is because the rates table is kept per station and not per TID.

2014-09-21iwlwifi: mvm: report all BA notifs to RSEyal Shapira
Currently BA notifications which don't reclaim any frames would not cause the RS to be called as no skbs are passed to mac80211. This is not optimal as RS can benefit from the statistics of sent vs. acked of such a BA. This can improve the reaction time of the RS algorithm. Also, an upcoming change in the firmware would cause BA timeout to be reported as a BA notif with 0 acked so this change is required for that as well.

2014-09-16iwlwifi: mvm: prepare for scheduler config commandAvri Altman
The scheduler is a HW sub-block that directs the work of the Flow Handler by issuing requests for frame transfers, specifying source and destination. Its primary function is to allocate flows into the TX FIFOs based upon a pre-determined mapping. The driver has some responsibilities to the scheduler, namely initialising and maintaining the hardware registers. This is currently done by directly accessing them, which can cause races with the firmware also accessing the registers. To address this problem, change the driver to no longer directly access the registers but go through the firmware for this if the firmware has support for DQA and thus the new command.

When not updating the quota, the new command shouldn't be stored as otherwise slowly drifting quota would never update the firmware. Fix this by storing the command only when it was also sent. Since the error message also only makes sense when attempting to send the command, just short-circuit the function when there's no need to send the command.

2014-09-14iwlwifi: mvm: use the firmware to get the temperature during CT killLuciano Coelho
Reading the temperature directly from the hardware, without the help of the firmware, is a complex process and is not entirely the same for different hardware. Also, some NICs don't easily allow access to the sensors when the firmware is not running, which would add even more complexity to the code. To reduce the code complexity and to avoid code duplication between the firmware and the driver, boot the firmware briefly to read the current temperature while in CT kill mode.

2014-09-14iwlwifi: mvm: don't update quota in firmware too oftenJohannes Berg
When updating quota in the firmware, it has to reset quite a bit of internal state, which apparently can have an adverse impact on its operation. Avoid that by only updating the quota command when there are any signification changes, i.e. added/removed bindings or changes in quota that are bigger than 8 TU within a binding.
