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]>

2016-02-24iwlwifi: mvm: move TX PN assignment for TKIP to the driverEliad Peller3-6/+13
If protocol offloading is configured, the fw might generate some frames (e.g. arp response) on its own during d3/d0i3. On d3/d0i3 exit the driver queries the updated PN (if relevant), and updates its keys (for the d0i3 case, this is done by iwl_mvm_d0i3_exit_work(), which is scheduled on d0i3 exit) While in d0i3, iwlmvm defers tx frames until d0i3 exit, and then continues their processing. This is problematic with TKIP, since the frame's PN has already been set at this stage (in contrast to CCMP, where the PN is being set only later on), so both the frame's PN and the upcoming PN update (from d0i3 exit work) might be wrong. Fix it by moving the TX PN assignment (for TKIP) to the driver, similarly to CCMP.

2016-02-16iwlwifi: mvm: inc pending frames counter also when txing non-staLiad Kaufman1-0/+9
Until this patch, when TXing non-sta the pending_frames counter wasn't increased, but it WAS decreased in iwl_mvm_rx_tx_cmd_single(), what makes it negative in certain conditions. This in turn caused much trouble when we need to remove the station since we won't be waiting forever until pending_frames gets 0. In certain cases, we were exhausting the station table even in BSS mode, because we had a lot of stale stations. Increase the counter also in iwl_mvm_tx_skb_non_sta() after a successful TX to avoid this outcome.

2016-02-15iwlwifi: pcie: fix RF-Kill vs. firmware load raceEmmanuel Grumbach3-82/+123
When we load the firmware, we hold trans_pcie->mutex to avoid nested flows. We also rely on the ISR to wake up the thread when the DMA has finished copying a chunk. During this flow, we enable the RF-Kill interrupt. The problem is that the RF-Kill interrupt handler can take the mutex and bring the device down. This means that if we load the firmware while the RF-Kill switch is enabled (which will happen when we load the INIT firmware to read the device's capabilities and register to mac80211), we may get an RF-Kill interrupt immediately and the ISR will be waiting for the mutex held by the thread that is currently loading the firmware. At this stage, the ISR won't be able to service the DMA's interrupt needed to wake up the thread that load the firmware. We are in a deadlock situation which ends when the thread that loads the firmware fails on timeout and releases the mutex. To fix this, take the mutex later in the flow, disable the interrupts and synchronize_irq() to give a chance to the RF-Kill interrupt to run and complete. After that, mask all the interrupts besides the DMA interrupt and proceed with firmware load. Make sure to check that there was no RF-Kill interrupt when the interrupts were disabled.
