* iwlwifi: mvm: add support for GCMP encryptionAyala Beker2016-07-061-1/+2
| | | | | | | | | | | | | | | | Newer hardware supports GCMP and GCMP 256-bit ciphers. Add support for adding/setting GCMP key for TX mode. In the TX command handling GCMP-256 is handled in a different way as the key size should be up to 128-bits: Set the key value to the key index in the key table, and specify that this key should be taken form the key table instead of from the TX command. While at it - convert security control flags to an enum. Signed-off-by: Ayala Beker <ayala.beker@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: support dqa queue sharingLiad Kaufman2016-07-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | Support DQA queue sharing when no free queue exists for allocation to a STA that already exists. This means that a single queue will serve more than a single TID (although the RA will be the same for all TIDs served). We try to choose the lowest AC possible, to ensure the shared queues have the lowest possible combined AC requirements. The queue to share is chosen only from the same RA's DATA queues as follows (in descending priority): 1. An AC_BE queue 2. Same AC queue 3. Highest AC queue that is lower than new AC 4. Any existing AC (there always is at least 1 DATA queue) If any aggregations existed for any of the TIDs of the shared queue - they are stopped (the FW is notified), but no delBA is sent.

* iwlwifi: mvm: change scan timeout to a delayed workLuca Coelho2016-07-061-2/+2
| | | | | | | | | Some transports may sleep when writing to registers, which is done when calling iwl_force_nmi(). So we can't call iwl_force_nmi() in a timer context. To solve that, convert the scan timeout timer to a delayed work. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: mvm: support dqa queue inactivation upon timeoutLiad Kaufman2016-07-061-1/+16
| | | | | | | | | | | | | | Support marking queues as inactive upon a timeout expiring, and allow inactive queues to be re-assigned to other RA/TIDs if no other queue is free. This is done by keeping a timestamp of the latest frame TXed for every RA/TID, and then going over the queues currently in use when a new queue is needed, inactivating all those that are inactive.

| | | | | | | | | | | | In non-shared queues, DQA requires re-configuring existing queues to become aggregated rather than allocating a new one.

* iwlwifi: mvm: add a new mvm reference type for RX dataLuca Coelho2016-05-101-0/+1
| | | | | | | | | | | | When a data packet is received, we need to make sure that we stay awake until it can be processed and wait a while before trying to enter runtime_suspend os system_suspend again. To do so, add a new reference type for RX data and take the reference when sending the packet to mac80211. We only do this for data packets, all the other RX packets sent by the firmware (e.g. notifications) are not a reason to prevent suspend. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: wake from runtime suspend before sending sync commandsLuca Coelho2016-05-101-0/+1
| | | | | | | | | | | | If a host command was queued while in runtime suspend, it would go out before the D0I3_END_CMD was sent. Sometimes it works, but sometimes it fails, and it is obviously the wrong thing to do. To fix this, have the opmode take a reference before sending a SYNC command and make the pcie trans wait for the runtime state to become active before actually queueing the command.

* iwlwifi: mvm: add reorder timeout per frameSara Sharon2016-05-101-0/+12
| | | | | | | | | | | | | | | | | | | | | | | Add a timer in order to release expired frames from the reorder buffer. This is needed since some APs do not retransmit frames to fill in the reorder holes and in TCP it results with a complete stall of traffic. This has a few side effects on the general design: The nssn may not reflect the the head of the reorder buffer. This situation is valid, and packets with SN lower than the reorder buffer head will be dropped. Another side effect is that since the reorder timer might expire we need to lock the reorder buffer. This however is fine since the locking is only inside a single reorder buffer between RX path and reorder timeout and there is no outside contention.

* iwlwifi: mvm: add reorder buffer per queueSara Sharon2016-05-101-0/+24
| | | | | | | | | | | | | | | | | | | | | | | Next hardware will direct packets to core based on the TCP/UDP streams. This logic can create holes in reorder buffer since packets that belong to other stream were directed to a different core. However, those are valid holes and the packets can be indicated in L3 order. The hardware will utilize a mechanism of informing the driver of the normalized ssn and the driver shall release all packets that SN is lower than the nssn. This enables managing the reorder across the queues without sharing any data between them. The reorder buffer is allocated and released directly in the RX path in order to avoid various races between control path and rx path. The code utilizes the internal messaging to notify rx queues of when to delete the reorder buffer.

* iwlwifi: mvm: add infrastructure for tracking BA session in driverSara Sharon2016-05-101-0/+25
| | | | | | | | | | | | | | | | According to the spec when a BA session is started there is a timeout set for the session in the ADDBA request. If there is not activity on the TA/TID then the session expires and a DELBA is sent. In order to check for the timeout, data must be shared among the rx queues. Add a timer that runs as long as BA session is active for the station and stops aggregation session if needed. This patch also lays the infrastructure for the reordering buffer which will be enabled in the next patches.

* iwlwifi: mvm: change RX sync notification to be an attribute and not a typeSara Sharon2016-05-101-0/+3
| | | | | | | | | | Currently the sync notification is a type of notification. However, it is better fitted as an attribute of a notification, since there might be another message in the payload (delba for instance) that should be sent while control path is waiting for all queues to process.

| | | | | | | | | | | | | | mac80211 will call the driver whenever there is a race between RSS queues and control path that requires a processing of all pending frames in RSS queues. Implement that by utilizing the internal notification mechanism: queue a message to all queues. When the message is received on a queue it decrements the atomic counter. This guarantees that all pending frames in the RX queue were processed since the message is in order inside the queue.

* iwlwifi: mvm: support bss dynamic alloc/dealloc of queuesLiad Kaufman2016-03-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | "DQA" is shorthand for "dynamic queue allocation". This enables on-demand allocation of queues per RA/TID rather than statically allocating per vif, thus allowing a potential benefit of various factors. Please refer to the DOC section this patch adds to sta.h to see a more in-depth explanation of this feature. There are many things to take into consideration when working in DQA mode, and this patch is only one in a series. Note that default operation mode is non-DQA mode, unless the FW indicates that it supports DQA mode. This patch enables support of DQA for a station connected to an AP, and works in a non-aggregated mode. When a frame for an unused RA/TID arrives at the driver, it isn't TXed immediately, but deferred first until a suitable queue is first allocated for it, and then TXed by a worker that both allocates the queues and TXes deferred traffic. When a STA is removed, its queues goes back into the queue pools for reuse as needed.

* iwlwifi: mvm: add LQM vendor command and notificationAviya Erenfeld2016-03-301-0/+12
| | | | | | | | | | | | | | | | | | | | | LQM stands for Link Quality Measurement. The firmware will collect a defined set of statitics (see the notification for details) that allow to know how busy the medium is. The driver issues a request to the firmware that includes the duration of the measurement (the firmware needs to be on channel for that amount of time) and the timeout (in case the firmware has a lot of offchannel activities). If the timeout elapses, the firmware will send partial results which are still valuable. In case of disassociation / channel switch and alike, the driver is in charge of stopping the measurements and the firmware will reply with partial results. The user space API for now is debugfs only and will be implmemented in an upcoming patch.

* | iwlwifi: mvm: add RSS queues notification infrastructureSara Sharon2016-02-271-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

| | | | | | | | | | | | | | | | | | | | Previous patches enabled the multi-queue rx path based on iwl_mvm_has_new_rx_api() which returned false by default. Change it to return the actual value based on the firmware TLV which is now defined. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
