2014-06-25mac80211: split sched scan IEsDavid Spinadel
Split sched scan IEs to band specific and not band specific blocks. Common IEs blocks may be sent to the FW once per command, instead of per band. This allows optimization of size of the command, which may be required by some drivers (eg. iwlmvm with newer firmware version). As this changes the mac80211 API, update all drivers to use the new version correctly, even if they don't (yet) make use of the split data.

2014-06-25mac80211: support more than one band in scan requestDavid Spinadel
Some drivers (such as iwlmvm) can handle multiple bands in a single HW scan request. Add a HW flag to indicate that the driver support this. To hold the required data, create a separate structure for HW scan request that holds cfg scan request and data about different parts of the scan IEs. As this changes the mac80211 API, update all drivers using it to use the correct new function type/argument.

2014-06-24iwlwifi: mvm: Fix broadcast filteringIlan Peer
Current code did not allow sending the broadcast filtering command for P2P Client interfaces. However, this was not enough, since once broadcast filtering command was issued over the station interface after the P2P Client connected, the command also attached the filters to the P2P Client MAC which is not allowed (FW ASSERT 1063).

2014-06-24iwlwifi: mvm: BT Coex - avoid the shared antenna for management framesEmmanuel Grumbach
If BT is active, we need to refrain from using the shared antenna. This logic is done in the firmware when we use the link quality tables. But for management frames, the rate is written in the Tx command by the driver. Hence the driver needs to make sure not use the shared antenna when BT is active for any frames that don't use the rate scale table such as management frames or multicast.
