2016-02-27iwlwifi: mvm: kill iwl_mvm_enable_agg_txqEmmanuel Grumbach1-5/+11
iwl_mvm_enable_agg_txq has only one user. Kill it and adapt the call site. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2016-02-27iwlwifi: mvm: add duplicate packet detection per rx queueSara Sharon1-0/+14
Next hardware will direct TCP/UDP streams to different cores. Packets belonging to the same stream will be directed to the same core. The result is that duplicates will be always directed to the same rx queue were the first packet was received. This enabled parallelizing the duplicate packet detection across the different cores, without sharing data between the rx queues.

If the peer allows, we can have A-MSDU inside A-MDPU. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2016-02-01iwlwifi: mvm: add new ADD_STA command versionSara Sharon1-9/+31
The 9000 hardware introduces the frame releaser, which keeps track of the aggregation window and notifies host of the window status. This requires in turn updating the hardware with the RX BA session window size. Firmware API was changed to enable that, update the driver accordingly.

2016-02-01iwlwifi: mvm: change the check for ADD_STA statusSara Sharon1-5/+5
The firmware will return the baid for BA session in the ADD_STA command response. This requires masking the check of the status, which is actually only 8 bits, and not the whole 32 bits.

2015-12-20iwlwifi: mvm: Change number of associated stations when station becomes ↵Ayala Beker1-5/+0
associated Currently, the number of associated stations gets updated when adding a new station or removing it. This is incorrect as it's possible that a station was inserted before it was associated Fix this by increasing/decreasing ap_assoc_sta_count whenever a station transitions in/out the associated state.

2015-12-20iwlwifi: mvm: change iwl_mvm_get_key_sta_id() to return the stationJohannes Berg1-31/+22
The code in iwl_mvm_update_tkip_key() is now pretty much duplicated with the code in iwl_mvm_get_key_sta_id() doing the station ID lookup again after it was already done. Change iwl_mvm_get_key_sta_id() to iwl_mvm_get_key_sta(), returning the mvm_sta pointer, to allow that duplicate code to be removed.

2015-12-20iwlwifi: mvm: Add a station in monitor modeChaya Rachel Ivgi1-3/+30
Currently when creating a new vif in monitor mode the driver doesn't allocate a specific station. This causes that in the situation that tx traffic is injected, the tx queues are not scheduled, with the result of a TFD queue hang. Fix that by allocating a station and ensuring its tx queues are scheduled.

2015-12-20iwlwifi: mvm: refactor the way fw_key_table is handledLuca Coelho1-6/+4
Instead of keeping the fw_key_table bits set when the keys are removed (i.e. in D3 entry or HW_RESTART flows), clear them and set them again only when the keys have been successfully re-added. This makes the bitmask more closely tied to the actual firmware programming. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-12-13iwlwifi: mvm: close the SP if we send fewer frames than expected in SPEmmanuel Grumbach1-1/+5
When we have holes in the BA window, there might be frames that have been ACKed between the read and the right pointers. This means that these frames won't be scheduled again by the SCD and the firwmare won't see them. This invalidates the number of frames we tell the firmware to send. When we detect this case, tell mac80211 to close the SP and to send an EOSP so that the firmware can be in sync. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-12-13iwlwifi: block the queues when we send ADD_STA for uAPSDEmmanuel Grumbach1-1/+6
We send an ADD_STA to instruct the firmware to release frames despite the peer being in PS. Since the ADD_STA command and the Tx frame that comes immediately afterwards can be reordered by the DMA engine, we need to block the Tx queues until the firmware replies with the ADD_STA response.

2015-12-13iwlwifi: mvm: set default new STA as non-aggregatedLiad Kaufman1-0/+2
When sending the first ADD_STA HCMD for a STA, the %add_modify field indicates an addition of a STA and not a modification of one. In such a case, all fields of the HCMD are used to initialize the corresponding fields in the FW, regardless of what bits are set in %modify_mask. Set the %tid_disable_tx field to mvm_sta->tid_disable_agg in iwl_mvm_sta_send_to_fw(). If the STA is only updated this will have no effect, but if it is added - it will make sure the STA starts with the correct queues - if any - configured as non-aggregated by default (until told otherwise).
