2021-08-26iwlwifi: mvm: clean up number of HW queuesJohannes Berg1-1/+1
Since switching to mac80211 TXQs, we no longer need to advertise more hardware queues than ACs, since we don't even set QUEUE_CONTROL anyway, so the vif->hw_queue[] mapping array won't be used. All we need (at least for now) is for hw->queues to indicate that we have enough queues to handle QoS.

2021-08-26iwlwifi: mvm: avoid static queue number aliasingJohannes Berg2-16/+38
When TVQM is enabled (iwl_mvm_has_new_tx_api() is true), then queue numbers are just sequentially assigned 0, 1, 2, ... Prior to TVQM, in DQA, there were some statically allocated queue numbers: * IWL_MVM_DQA_AUX_QUEUE == 1, * both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and * IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9. Now, these values are assigned to the members mvm->aux_queue, mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by default. Normally, this doesn't really matter, and if TVQM is in fact available we override them to the real values after allocating a queue for use there. However, this allocation doesn't always happen. For example, for mvm->p2p_dev_queue (== 2) it only happens when the P2P Device interface is started, if any. If it's not started, the value in mvm->p2p_dev_queue remains 2. This wouldn't really matter all that much if it weren't for iwl_mvm_is_static_queue() which checks a queue number against one of those four static numbers. Now, if no P2P Device or monitor interface is added then queue 2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously returns true for it. If it then gets full, all interface queues are stopped, instead of just backpressuring against the one TXQ that's really the only affected one. This clearly can lead to issues, as everything is stopped even if just a single TXQ filled its corresponding HW queue, if it happens to have an appropriate number (2 or 9, AUX is always reassigned.) Due to a mac80211 bug, this also led to a situation in which the queues remained stopped across a deauthentication and then attempts to connect to a new AP started failing, but that's fixed separately. Fix all of this by simply initializing the queue numbers to the invalid value until they're used, if TVQM is enabled, and also setting them back to that value when the queues are later freed again.

2021-08-26iwlwifi: mvm: set replay counter on key installJohannes Berg1-0/+53
When installing a (new) key, set the replay counter so that after FW restart the firmware has the correct value of the replay counters. This doesn't have a large effect - for frames that reach the driver, it will do a replay check, and when installing a new key, the counter is normally zero to start with (not for GTK though, if joining the BSS for the first time). Since this only affects frames handled entirely by the FW, and that's restricted to a few unicast management frames, the only affect here is for those after a firmware restart.

2021-06-22iwlwifi: mvm: honour firmware SMPS requestsJohannes Berg3-0/+54
The firmware can now request SMPS (due to thermal conditions), add some code to honour such requests and bubble them up through the stack, subject to our other SMPS constraints, e.g. from Bluetooth. Then, if the firmware requests SMPS, then we know that it supports a small extension to the PHY configuration API where a chain mask of 0 means "use 1 but pick which one yourself", so in this case we use that extension. During firmware restart, we stay in the previous state, and the FW will send us a notification at startup (only) if the temperature is below the lower or above the high threshold, to sync the state.

SMPS requests may differ per interfaces due to e.g. Bluetooth only interfering on 2.4 GHz, so if that's the case we should, in the case of multiple PHY contexts, still allow RX diversity on PHY context that have no interfaces with SMPS requests.

2021-06-22iwlwifi: mvm: don't change band on bound PHY contextsJohannes Berg1-6/+18
When we have a P2P Device active, we attempt to only change the PHY context it uses when we get a new remain-on-channel, if the P2P Device is the only user of the PHY context. This is fine if we're switching within a band, but if we're switching bands then the switch implies a removal and re-add of the PHY context, which isn't permitted by the firmware while it's bound to an interface. Fix the code to skip the unbind/release/... cycle only if the band doesn't change (or we have old devices that can switch the band on the fly as well.)

Note that this is relevant only for old devices that still use the TIME_EVENT firmware API for channel switch. The check that we hear a beacon before the time event ends was meant to be used for the association time event and not for the channel switch time event.
