2015-03-02iwlwifi: add new TLV capability flag for BT PLCREmmanuel Grumbach1-2/+2
Packet Level Co-Running is a BT Coex feature which is supported on certain devices only, hence the need for a TLV flag for it. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-01-22iwlwifi: mvm: BT Coex - set all the co-running values to 0Emmanuel Grumbach1-8/+8
With this value, we de-facto disable the feature. Since it is not working yet, disable it completely. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2014-11-11iwlwifi: mvm: rs - don't use the shared antenna when BT load is highEmmanuel Grumbach1-0/+16
When we need only one antenna, we should refrain from using the antenna that is shared with BT if BT load is high. Fix this. Reviewed-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2014-09-14iwlwifi: define the non shared antenna per hardwareEmmanuel Grumbach1-0/+4
The sharing model will differ in new hardware. Define the non shared antenna based on the device so that different devices can have different names for the non shared antenna. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2014-09-08iwlwifi: mvm: BT Coex - always initialize smps_modeJohannes Berg1-4/+3

Leave it to default instead - regardless of the BT activity. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-07-22iwlwifi: mvm: BT Coex - fix the ACK / CTS kill maskEmmanuel Grumbach1-95/+75
According to new requirements, the ACK / CTS kill mask is not related to reduced TX power anymore. This allows to remove the code that tracked reduced TX power enablement across different interfaces. The ACK / CTS kill mask is now fetch from a table. It depends on the Activity grading (activity from BT) and on the Look Up Table (LUT) type.

2014-07-07iwlwifi: mvm: BT Coex - relax constraints when TTC / RRC is activeEmmanuel Grumbach1-9/+12
When TxTxCo-Running is active, we can relax the constraints on the rate control. When RxRxCo-Running is active, we can relax the constrains on SMPS. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Start the new BT Coex implementation. Don't react to notifications for now - only the initial configuration is implemented. The rest will happen in next patches. Since coex.c now uses the new the new structures in all functions, we need to adapt the code to compile, even if it doesn't run yet. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-07-07iwlwifi: mvm: BT Coex - prepare towards new APIEmmanuel Grumbach1-15/+69
A new API is coming. This new API is not backward compatible. So we need to keep the old commands to be able to work with the former API. Move all the current code into a new file: coex_legacy. If a firmware with the new API is detected, we currently just bail out since the implementation of the new API will come in future patches.

2014-06-24iwlwifi: mvm: BT Coex - avoid the shared antenna for management framesEmmanuel Grumbach1-0/+5
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.

2014-05-15iwlwifi: mvm: BT Coex - send channel inhibition before associationEmmanuel Grumbach1-30/+17

In order to debug the firmware, we need to be able to set the BT priority of WiFi packets. This priority is set based on the type of the packet (control frames, EAPOL etc...). For debugging purposes, allow to override this priority by a debugfs controlled value. Enable this feature that needs this priority to be able to test it.

We can now define the priority against BT per AC. This is possible with a newer firmware that allows to define the priority with 2 bits. Note that this change is compatible with older firmware since older firmware will simply ignore the new bit (11), and we still set the old bit (12) in the same cases as before.
