2016-03-03ath10k: fix pointless update of peer stats listMohammed Shafi Shajakhan1-2/+4
We periodically receive f/w stats event for updating the rx duration and there is no reason to keep on appending the f/w stats peer list, as this gets completely cleaned up when the user polls for f/w stats {pdev, vdev, peer stats}. Only don't print the warning message in the case PEER_STATS service is enabled Fixes: 856e7c3 ("ath10k: add debugfs support for Per STA total rx duration") Signed-off-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2016-03-02iwlwifi: pcie: detect and workaround invalid write ptr behaviorSara Sharon1-4/+13
In 9000 series A0 step the closed_rb_num is not wrapping around properly. The queue is wrapping around as it should, so we can W/A it by wrapping the closed_rb_num in the driver. While at it, extend RX logging and add error handling of other cases HW values may cause us to access invalid memory locations. Add also a proper masking of vid value read from HW - this should not have actual affect, but better to be on the safe side.

2016-03-02iwlwifi: mvm: update ucode status before stopping deviceChaya Rachel Ivgi5-9/+12
Leaving ucode_loaded to true after stop_device() has been called is a recipe for problems. Flows that are not sync'ed with the driver life cycle (like debugfs hooks and thermal hooks) must check that the firmware is loaded before they interact with it. Therefore we need to keep this variable updated with the real status of the firmware. Signed-off-by: Chaya Rachel Ivgi <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>

Till today, the ucode consisted of two d0 images - regular, in which the usniffer wasn't enabled, and usniffer, in which the usniffer logs were enabled. Lately, the two images were unified, so there is only one d0 image, in which the usniffer logs are enabled. Add new TLV capability for supporting the consolidated images (set 2, bit 13).

2016-02-28iwlwifi: mvm: Disable beacon storing in D3 when WOWLAN configuredMatti Gottlieb1-2/+1
Currently when entering D3 with WOWLAN configured, we enable in the configuration flags beacon storing, and do not disable beacon filtering, and do not wake up from a magic packet. Having both enabled is wrong (should not have both enabled), and causes problems in the RX queues in the FW, causing the FW not to recognize the magic packet when it comes.

2016-02-27iwlwifi: mvm: take care of padded packetsSara Sharon1-7/+23
To ensure that the SNAP/TCP/IP headers are DW aligned, the firmware may add 2-byte pad at the end of the mac header - after the IV, before the SNAP. In that case the mpdu descriptor pad bit will be turned on. Driver should take it into consideration, and remove the padding before passing the packet to mac80211. Do that.

2016-02-27iwlwifi: mvm: Send power command on BSS_CHANGED_BEACON_INFO if neededAvri Altman1-1/+6
Beacon abort (ba) is set while sending power command, but only after at least one beacon_filter command was successfully sent. If we heard a beacon before starting association, this order is maintained and ba is properly set. However, if the first beacon is received after association, we send the power command upon association, configure the beacon filtering when the first beacon arrives, and in that case, beacon abort is not set. So identify this, and send a power command post the beacon_filter command if needed. Signed-off-by: Avri Altman <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>

2016-02-27iwlwifi: mvm: support VHT MU-MIMO notificationSara Sharon4-2/+49
When the device is in d0i3/d3 we will not receive the VHT MU-MIMO group id management frame. Instead, firmware will notify us upon exit on the current status and we can in turn update mac80211. Support this notification. While at it, also check as a precaution that the vif is indeed the VHT MU-MIMO owner before updating the firmware.

2016-02-27iwlwifi: mvm: add RSS queues notification infrastructureSara Sharon5-0/+114
In multi rx queue HW, without execessive locking, there is no sync between the ctrl path (default queue) and the rest of the rx queues. This might cause issues on certain situations. For example, in case a delBA was processed on a default queue but out of order packets still wait for processing on the other queue. The solution is to introduce internal messaging between the CTRL path and the other rx queues. The driver will send a message to the firmware, which will echo it to all the requested queues. The message will be in order inside the queue. This way we can avoid CTRL path and RSS queues races. Add support for this messaging mechanism. As the firmware is agnostic to the data sent, add internal representation of the data as well. Although currently only delBA flow will use it, the internal representation will enable generic use of this infrastructure for future uses. Next patch will utilize this messaging mechanism for the reorder buffer delBA flow. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-02-27iwlwifi: mvm: add duplicate packet detection per rx queueSara Sharon3-1/+92
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.

2016-02-27iwlwifi: mvm: support filtered frames notificationSara Sharon4-0/+77
During d0i3 frames might be filtered by the FW and this may cause reordering buffer a delay - as the frames will not be received and reorder will time out.

2016-02-27iwlwifi: mvm: update rx_status with mactime flagSara Sharon3-5/+7
When forming IBSS, mac80211 scans in order to find an already existing cell to join. In case the scan does not find any existing cell a new IBSS cell is formed. When receiving the beacons of another IBSS cell we should merge if the other IBSS cell's TSF is higher than ours. However, currently iwlmvm does not set any timestamp flag in rx_status so there is no valid rx timestamp to compare the beacon's TSF to. The reason for that is that TSF as indicated by the firmware is at INA time, but up till now mac80211 expected the TSF at the beginning or end of the MPDU. Set the flag to the newly added RX_FLAG_MACTIME_PLCP_START flag. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>

2016-02-27iwlwifi: mvm: handle pass all scan reportingLuca Coelho3-5/+44
The firmware doesn't send match found notifications when no matchsets are passed. This makes sense because if there are no matchsets, nothing can be matched. But the nl80211 API should report when there are results available, even if no matchsets were passed. To handle this, we can use the firmware's ITERATION_COMPLETE reporting, which will send us notifications every time it completed a scheduled scan iteration. Then we can set a flag when we received beacons and use that to report that results are available. Signed-off-by: Luca Coelho <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
