* iwlwifi: print warning on request_module failureJohannes Berg2013-04-08
| | | | | | | | | | | 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.

Also, this function can always look at mvm->last_bt_notif provided that the latter is updated on time.

* iwlwifi: mvm: clean up invalid station handlingEmmanuel Grumbach2013-04-03
| | | | | | | | | | | | | 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.

* iwlwifi: sleep for at least 10 secondsJohannes Berg2013-04-03
| | | | | | | | | | | | | | | | 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.

Use this number as the initial security sequence number after recovery. This consolidates security sequence handling for both chip families, as we no longer have to rely on 12xx specific Tx completion. A fortunate side effect of this is correct management of seq numbers for AP roles and multi-role scenarios. When a link is removed we save the last seq number on a persistent part of the wlvif. This helps the data survive through recoveries/suspends, which also entail changes in the hlid of the link. This functionality is STA only currently.
