2013-04-08iwlwifi: mvm: remove users of nvm_data->valid_tx_antEmmanuel Grumbach
In commit 332235427a566d8be04b9676a7ac380c8853aa9b "iwlwifi: mvm: take the valid_{rx,tx}_ant from the TLV" I replaced the access to nvm_data->valid_tx_ant to an inline cheking the TLV flags but forgot a few occurences. Fix that.

2013-04-03iwlwifi: mvm: rename iwl_mvm_new_bt_coex_notifEmmanuel Grumbach

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: set keepalive period regardless of PM stateAlexander Bondar
The firmware starts sending nulldata frames for keepalive immediately after association, regardless of power management state. The driver thus needs to configure keep alive period unconditionally.

2013-04-03iwlwifi: mvm: always send power table commandAlexander Bondar
The driver distinguishes between power management and device's power down enablement. Power management enablement depends both on driver's module power parameters and mac80211 decision. The device's power down depends only on driver's module power parameters. Change the driver to always send Power Table command to enable or disable both power management and device's power down.

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. The driver verifies number of created interfaces and disables power management when multiple interfaces 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.
