2013-06-05mac80211: Use suitable semantics for beacon availability indicationAlexander Bondar
Currently beacon availability upon association is marked by have_beacon flag of assoc_data structure that becomes unavailable when association completes. However beacon availability indication is required also after association to inform a driver. Currently dtim_period parameter is used for this purpose. Move have_beacon flag to another structure, persistant throughout a interface's life cycle. Use suitable sematics for beacon availability indication.

2013-06-05iwlwifi: mvm: fix MCAST in AP modeEmmanuel Grumbach
In multicast, there is no retries nor RTS since there is no specific recipient that can ACK or send CTS. This means that we must not use the rate scale table for multicast frames.

2013-06-05iwlwifi: mvm: enable PM always in unassociated modeAlexander Bondar
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.

2013-06-04iwlwifi: mvm: correctly configure MCAST in AP modeEmmanuel Grumbach
The AP mode needs to use the MCAST fifo for the MCAST frames sent after the DTIM. This fifo needs to be configured with the same parameters as the VOICE FIFO. A separate SCD queue is mapped to this fifo - the cab_queue (cab stands for Content After Beacon). This queue isn't connected to any station, but rather to the MAC context. This queue should (and is already) be set as the MCAST queue - this is part of the of MAC context command.

2013-06-04iwlwifi: mvm: Fix quota command settingsIlan Peer
According to the FW implementation, the quota command should have a valid entry for each active binding (where 'active' in this context means that the binding is known to the FW). In case the binding should not get any quota, the 'quota' should be set to zero. Not setting an 0 quota for an active binding when all the MACs in the binding are idle, i.e., not associated in case of managed interface, will result in preventing the FW scheduler from entering IDLE state and the FW from transitioning to low PS.

2013-05-29iwlwifi: mvm: implement D3 testingJohannes Berg
For testing the D3 (WoWLAN) firmware, it is useful to be able to run the firmware with instrumentation while the host isn't sleeping and can poke at the firmware debug logging etc. Implement this by a debugfs file. When the file is opened the D3 firmware is loaded and all regular commands are blocked. While the file is being read, poll the firmware's PME status flag and report EOF once it changes to non-zero. When it is closed, do (most of) the resume processing. This lets a user just "cat" the file. Pressing Ctrl-C to kill the cat process will resume the firwmare as though the platform resumed for non-wireless reason and when the firmware wants to wake up reading from the file automatically completes. Unlike in real suspend, only disable interrupts and don't reset the TX/RX hardware while in the test mode. This is a workaround for some interrupt problems that happen only when the PCIe link isn't fully reset (presumably by changing the PCI config space registers which the core PCI code does.) Note that while regular operations are blocked from sending commands to the firmware, they could still be made and cause strange mac80211 issues. Therefore, while using this testing feature you need to be careful to not try to disconnect, roam or similar, and will see warnings for such attempts. Als note that this requires an upcoming firmware change to tell the driver the location of the PME status flag in SRAM. D3 test will fail if the firmware doesn't report the pointer.
