* iwlwifi: mvm: Disable uAPSD for D3 imageAlexander Bondar2013-10-02
| | | | | | | | | The D3 firmware image doesn't support uAPSD, so disable it. Signed-off-by: Alexander Bondar <alexander.bondar@intel.com> Reviewed-by: Guy Cohen <guy.cohen@intel.com> Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* iwlwifi: mvm: Add PBW snoozing enablementAlexander Bondar2013-08-16
| | | | | | | | | | | The Performance Based Window snooze mechanism is based on uAPSD and is used in low-medium traffic scenarios, in order to provide better power performance while insuring low latency and jitter for the incoming traffic. This patch enables PBW snoozing in case uAPSD is enabled and all ACs are uAPSD trigger and delivery enabled.

* iwlwifi: mvm: Implement CQM offloadingAndrei Otcheretianski2013-08-16
| | | | | | | | | | | | Use beacon statistics notification to track RSSI. Notify mac80211 when the tresholds are crossed. The roaming treshold is configured to be equal to cqm_thold. If the beacon filtering command is not supported by fw fall back and use mac80211 mechanism.

* iwlwifi: mvm: Change beacon filtering commandHila Gonen2013-07-31
| | | | | | | | | | | | | | Change beacon filtering command due to a change in the API. In case the FW supports the old API, we do not send the BF HCMD and assume that since the corresponding struct in the FW is zeroed by default then we don't need to disable it in the FW actively.

* iwlwifi: mvm: Upgrade to a new power management uAPSD APIAlexander Bondar2013-07-16
| | | | | | | | | | | | Change power management implementation to support new host-device API containing uAPSD parameters. Verify FW support for this new API. Use the new power table command (0xA9) to configure power management. Use the legacy command (0x77) if FW does not support the new API. New file power_legacy.c is introduced for legacy implementation.

* iwlwifi: mvm: Add support for Low Power RXAlexander Bondar2013-06-25
| | | | | | | | | | | | To improve power consumption in idle associated mode FW may lower RX power. This low linearity mode is acceptable for listening low rate RX such as beacons and groupcast. The driver enables LPRX only if PM is enabled and associated AP's beacon TX rate is 1Mbps or 6Mbps. LPRX RSSI threshold is used to limit a range where LPRX is applied.

* iwlwifi: mvm: enable PM always in unassociated modeAlexander Bondar2013-06-05
| | | | | | | | | | | | | | | In unassociated BSS STA mode FW verifies both power save and power management flags to decide on switching power off. The driver currently sets power management flag according to mac80211 decision. As result, in unassociated mode power management flag is down and power consumption is high. Change power management enablement. When unassociated in BPS and LP power save modes enable power management regardless of mac80211 decision. Rely on mac80211 decision if associated. Add power management state update during associated/disassociated modes transitions.

* iwlwifi: mvm: Change number of DTIMs to skip semanticsAlexander Bondar2013-05-29
| | | | | | | | | | | | If skip over DTIMs is enabled the driver can specify number of DTIMs to skip. This parameter in host-device API implies number of DTIM periods to skip. For example, to skip one DTIM means sleep over two DTIM periods. Change semantics accordingly. Change this parameter's default value.
