2013-04-16iwlwifi: mvm: change TX/RX AM-to-PSM transition time for LP modeAlexander Bondar
Recently in low power (LP) mode FW moved from active to power save mode after TX/RX completion faster than in balanced power mode (BPS).

2013-04-16iwlwifi: mvm: fix first_antennaEmmanuel Grumbach
first_antenna is supposed to return the first antenna as a 0-based bitmap: ANT_A is BIT(0), ANT_B is BIT(1), etc... Since ffs is 1 based (ffs(BIT(0)) = 1), then we had an off-by-one bug: BIT(ffs(ANT_A)) = BIT(ffs(BIT(0))) = BIT(1) = ANT_B. So what we really want is: BIT(ffs(ANT_A) - 1) = BIT(ffs(BIT(0)) - 1) = BIT(0) = ANT_A.

2013-04-08iwlwifi: dvm: handle FLUSH ampdu actions from mac80211Emmanuel Grumbach
Until now we didn't handle properly the FLUSH ampdu action coming from mac80211. This could result in SCD queue leak: mac80211 would STOP_FLUSH an AMPDU Tx session and remove the station. If we had still packets on the ring, we wouldn't deallocate the SCD queue and wait for it to be empty. The indication of the queue being empty comes from the Tx response flow which relies on the tid_data structure. The problem is that this structure has been cleared when the station has been removed. In order to solve this issue, block in the STOP_FLUSH ampdu_action until the SCD queue is flushed, and only then, let mac80211 move forward to remove the station. iwlagn_txfifo_flush had to be enhanced to allow this. The bug fixed here caused the "txq_id mismatch: 12 0" print. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-04-08iwlwifi: print warning on request_module failureJohannes Berg
If request_module() failed then we didn't have the correct opmode module that the driver needs to function, so print a warning in this case to make it more obvious what could be wrong. This still won't catch the case where the module simply doesn't exist because it wasn't compiled though.

2013-04-03iwlwifi: mvm: clean up invalid station handlingEmmanuel Grumbach
Using IWL_MVM_STATION_COUNT and IWL_INVALID_STATION together isn't a good idea as they have different values. Always use IWL_MVM_STATION_COUNT for an invalid station in MVM and move the definition of the IWL_INVALID_STATION constant into the DVM driver to avoid making such mistakes again. The one use in the transport code can be hard-coded to -1 instead as the station ID is passed as an integer there.

2013-04-03iwlwifi: sleep for at least 10 secondsJohannes Berg
Many platforms have issues processing a wakeup signal while they're still suspending, and will ignore it. Since our device thinks it woke the platform, and the platform ignored the signal, it will sleep without WoWLAN being enabled as the device disables WoWLAN when having woken the platform. Resolve this by making the device wait for 10 seconds after getting the suspend signal before waking up the platform.

2013-04-03iwlwifi: mvm: don't disable power management due to P2P deviceAlexander Bondar
Currently power management is supported only when only a single virtual interface is present.

However, this rule does not extend to a P2P device that is handled differently in the firmware. If a P2P device is added power management can remain enabled.
