2024-05-29wifi: iwlwifi: mvm: handle BA session teardown in RF-killJohannes Berg
When entering RF-kill, mac80211 tears down BA sessions, but due to RF-kill the commands aren't sent to the device. As a result, there can be frames pending on the reorder buffer or perhaps even received while doing so, leading to warnings. Avoid the warnings by doing the BA session teardown normally even in RF-kill, which also requires queue sync.

2024-02-21wifi: iwlwifi: mvm: ensure offloading TID queue existsBenjamin Berg
The resume code path assumes that the TX queue for the offloading TID has been configured. At resume time it then tries to sync the write pointer as it may have been updated by the firmware. In the unusual event that no packets have been send on TID 0, the queue will not have been allocated and this causes a crash. Fix this by ensuring the queue exist at suspend time.

2024-02-08wifi: mac80211: introduce 'channel request'Johannes Berg
For channel contexts, mac80211 currently uses the cfg80211 chandef struct (control channel, center freq(s), width) to define towards drivers and internally how these behave. In fact, there are _two_ such structs used, where the min_def can reduce bandwidth according to the stations connected. Unfortunately, with EHT this is longer be sufficient, at least not for all hardware. EHT requires that non-AP STAs that are connected to an AP with a lower bandwidth than it (the AP) advertises (e.g. 160 MHz STA connected to 320 MHz AP) still be able to receive downlink OFDMA and respond to trigger frames for uplink OFDMA that specify the position and bandwidth for the non-AP STA relative to the channel the AP is using. Therefore, they need to be aware of this, and at least for some hardware (e.g. Intel) this awareness is in the hardware. As a result, use of the "same" channel may need to be split over two channel contexts where they differ by the AP being used. As a first step, introduce a concept of a channel request ('chanreq') for each interface, to control the context it requests. This step does nothing but reorganise the code, so that later the AP's chandef can be added to the request in order to handle the EHT case described above.

The firmware / hardware of devices supporting RSS is able to report duplicates and packets that time out inside the reoder buffer. We can now remove all the complex logic that was implemented to keep all the Rx queues more the less synchronized: we used to send a message to all the queues through the firmware to teach the different queues about what is the current SSN every 2048 packets. Now that we rely on the firmware / hardware to detect duplicates, we can completely remove the code that did that in the driver and it has been reported that this code was spuriously dropping legit packets.
