Function _rtl8821ae_mrate_idx_to_arfr_id is functionally identical to the generic version rtl_mrate_idx_to_arfr_id, so remove _rtl8821ae_mrate_idx_to_arfr_id and use the generic one instead. This also fixes a missing break statement found by CoverityScan in _rtl8821ae_mrate_idx_to_arfr_id, namely: CID#1167237 ("Missing break in switch") Thanks to Joe Perches for spotting this when I submitted an earlier patch.

The rs_rate_from_ucode_rate() function may return -EINVAL if the rate is invalid, but none of the callsites check for the error, potentially making us access arrays with index IWL_RATE_INVALID, which is larger than the arrays, causing an out-of-bounds access.

2018-10-08iwlwifi: mvm: kill INACTIVE queue stateJohannes Berg
We don't really need this state: instead of having an inactive state where we can awaken zombie queues again if needed, just keep them in their normal state unless a new queue is actually needed and there's no other way of getting one. We do this here by making the inactivity check not free queues unless instructed that we now really need to allocate one to a specific station, and in that case it'll just free the queue immediately, without doing any inactivity step inbetween. The only downside is a little bit more processing in this case, but the code complexity is lower. Additionally, this fixes a corner case: due to the way the code worked, we could only ever reuse an inactive queue if it was the reserved queue for a station, as iwl_mvm_find_free_queue() would never consider returning an inactive queue.

2018-10-08iwlwifi: mvm: make queue TID change more explicitJohannes Berg
Instead of iterating all the queues after having potentially changed some queue configurations, rechecking if that was done, mark the ones that do need a TID change explicitly in a bitmap and use that to send the change to the firmware. While at it, also rename iwl_mvm_change_queue_owner() to iwl_mvm_change_queue_tid() since that's more obvious - the "kind" of owner isn't immediately clear right now.

2018-10-08iwlwifi: mvm: remove RECONFIGURING queue stateJohannes Berg
We set the queue to this state, only to pretty much immediately move it out of it again. However, we can't even hit any of the code that checks if the queue is reconfiguring, because all of this happens under mvm->mutex and we hold the all the way from marking the queue as RECONFIGURING to marking it as READY again. Additionally, the queue that became RECONFIGURING would've been in SHARED state before, and it can safely stay in that state. In case of errors, it previously would have stayed in RECONFIGURING which it could never have left again. Remove the state entirely and just track the queues that need to be reconfigured in a separate, local, bitmap.

2018-10-08iwlwifi: mvm: reconfigure queues during inactivity checkJohannes Berg
We currently reconfigure the queues after the inactivity check, but only in one of the two callers. This might leave queues in a state where the TID owner is wrong, if called when reserving a queue for a new station. Clean this up and do the reconfiguration inside the inactivity check function. This requires changing the locking, but one of the two places already holds the mvm mutex and the other easily can.

2018-10-08iwlwifi: mvm: remove per-queue hw refcountJohannes Berg

2018-10-08iwlwifi: mvm: move queue management into sta.cJohannes Berg

2018-10-08iwlwifi: dump debug data before stop deviceShahar S Matityahu
Debug data dump is not working in flows that stop the device is used in their error handling. During these flows the op mode mutex is locked until the device stops. Because of that, any assert generated from the firmware can be handled only after the device already stopped. Since dumping cannot occour after stopping the device, split the the dump function to two parts, Part that handles locking, and the part that starts the actual dumping and call the second part in the op mode stop device function.

2018-10-08iwlwifi: mvm: use fast balance scan in case of DCM mode with P2P GOAyala Beker
Currently in case of DCM with P2P GO where BSS DTIM interval < 220 msec the fw fails to allocate events for the P2P GO dtim due to long passive scan events. Fix this by requesting all scans in this scenario to be fragmented with fast balance scan time settings. The only exception is in case fragmented scan was planned to be set due to low latency or high throughput reason, set the scan timing as planned.

2018-10-08iwlwifi: mvm: don't send keys when entering D3Sara Sharon
In the past, we needed to program the keys when entering D3. This was since we replaced the image. However, now that there is a single image, this is no longer needed. Note that RSC is sent separately in a new command. This solves issues with newer devices that support PN offload. Since driver re-sent the keys, the PN got zeroed and the receiver dropped the next packets, until PN caught up again.
