In a000 devices we will support up to 32 stations. The max station define is used also for invalid station marking which makes finding usages of actual maximum station pretty hard to sort through - change it to be a different define in order to make future changes easier. Use also ARRAY_SIZE intead of define when possible. Do not move yet to 32 stations until firmware do it though.

Currently multicast queue is associated with the broadcast station. This raises quite a few issues: The multicast queue has a special treatment: - It is sent in the MAC context command - It is excluded from tfd_queue_mask In DQA mode we end up enabling two queues - the probe response queue and the multicast queue - with the same station (broadcast) and TID while in DQA mode it should be unique RA-TID. Firmware will enforce it for a000 devices, so this allocation will fail. In addition, in a000 devices the FW will set the FIFO and not the driver. So there is a need for FW to know when we enable the queue that it is multicast queue so it will be bound to the multicast FIFO. There is no such way in current design. In order to simplify driver and firmware handling of this queue create a multicast station. This solves the unique RA-TID issue in the short term and serves as preparation for the long term. In the long term we will also add a flag marking this station for the FW as the multicast station. Once we will do that the FW will know this is the multicast queue immediately when it is added and bind it to the correct FIFO. It will also enable removing the special treatment of the queue in the MAC context command. Signed-off-by: NSara Sharon <sara.sharon@intel.com> Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

When a station is asleep, the fw will set it as "asleep". All queues that are used only by one station will be stopped by the fw. In pre-DQA mode this was relevant for aggregation queues. However, in DQA mode a queue is owned by one station only, so all queues will be stopped. As a result, we don't expect to get filtered frames back to mac80211 and don't have to maintain the entire pending_frames state logic, the same way as we do in aggregations. The correct behavior is to align DQA behavior with the aggregation queue behaviour pre-DQA: - Don't count pending frames. - Let mac80211 know we have frames in these queues so that it can properly handle trigger frames. When a trigger frame is received, mac80211 tells the driver to send frames from the queues using release_buffered_frames. The driver will tell the fw to let frames out even if the station is asleep. This is done by iwl_mvm_sta_modify_sleep_tx_count. Signed-off-by: NSara Sharon <sara.sharon@intel.com> Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

The session protection set for association is only removed when BSS_CHANGED_BEACON_INFO is set and BSS_CHANGED_ASSOC is not set. However, mac80211 may set both on association (in case a beacon was already received). In this case, mac80211 will not set BSS_CHANGED_BEACON_INFO on the next beacons because it has already notified the beacon change, so the session protection is never removed (until the session protection ends). When a CSA is received within this time, the station will fail to folllow the channel switch because it cannot schedule the time event. Fix this by removing the session protection when BSS_CHANGED_BEACON_INFO and BSS_CHANGED_ASSOC are both set.

A few of the static queues are enabled along with the bcast STA. Make sure they are removed along with it, rather than waiting for the mac ctxt release. This is needed because we sometimes have a STA being removed and then added again (either with the same sta_id or a different one). If we wait for the mac ctxt release we will try to allocate the queues again (as this is currently done in the STA allocation and not in the MAC init) although they weren't freed, and even if the sta_id of the STA has changed.

The firmware will soon actually look at the AID field, and when it does that it'll try to ensure that the AID is never changing. Due to the way the station is added, it may start with an invalid AID before it's associated, so to ensure a constant AID (once it becomes non-zero), track the station state and set the AID only when the station is associated and when it disassociates.

For a000 devices the INIT and RT images are unified to one image. The changes in the flow are the following: * Driver load only RT firmware - meaning that the nvm access command will be done in the RT image load flow. * A new command (NVM_ACCESS_COMPLETE) now signals to the FW that the driver is done accessing the NVM and FW can proceed with phy calibrations. * Phy DB is no longer sent from INIT FW to be restored by driver for the RT FW - all the phy DB is now internal to the FW. INIT complete will now follow the NVM access command, without phy DB calls before. * Paging command is sent earlier in the flow before NVM access to enable a complete load of FW. * caution must be care when restart is called since we may have not completed init flow even though we are in RT firmware.

Currently when configuring the cab queue the scheduler is configured without station id - which results in station id 0. In DQA mode this causes firmware to assert later on when the actual station 0 is added with an empty tfd_queue_mask. Fix that by configuring the queue to the broadcast station. This is a bit trickier since the queue should not be included in the tfd_queue_mask of the ADD_STA since it is a multicast queue, and the tfd_queue_mask is only unicast queue. As a result the queue should be enabled only after the broadcast station is added. Signed-off-by: NSara Sharon <sara.sharon@intel.com> Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

When using RSS on 9000 series devices, we can't rely on processing the received frames for station powersave handling, since they could be processed on different CPUs and out of order. In order to still manage the powersave of stations, the firmware sends a notification on sleep->wake, wake->sleep and - for U-APSD - frames received with PM while already sleeping (with the TID.) With this, the driver can set AP_LINK_PS, which is required for real parallel RX. In addition, this requires checking for PS-Poll frames and calling ieee80211_sta_pspoll() appropriately.

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.

"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.
