This flow can actually happen due to a corner case in mac80211: the station is deleted before we get a chance to reclaim all the packets in flight in AGG queue. The tid_data for this station is zeroed, and we lose the match with the Tx queue. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Since request_module_nowait() can't be backported use request_module() instead -- we don't need the asynchronous behaviour of request_module_nowait() here since we're running in the firmware request work struct.

For AGG queues, we must match between the WiFi sequence number and the TFD number. This is a HW (SCD) requirement. This is a take two of my iwlwifi: add debug in Tx path in AGG flow This will allow us to catch bad cases in which the packets aren't in the right place on the ring. which disappeared during code move.

When the driver is built into the kernel instead of a module when the system boots it results in a panic. The order things are built in results in their initialization order when built into the kernel. Wifi has to be initialized before mvm or dvm.

This locking isn't needed. The only locking we need is when we access prph registers but there is already a separate lock for that. Since we haven't returned from the mac80211's IEEE80211_AMPDU_TX_OPERATIONAL ampdu_action, we cannot receive any Tx frame for that sta / tid while enabling the queue.

Add locking to the dynamic loading code to prevent corrupting the list if multiple device ever init at the same time (which cannot happen for multiple PCI devices, but could happen when different busses init concurrently.) Also remove a device from the list when it stops so the list isn't left corrupted, including a fix from Don to not crash when it was never added.

Currently 4 channels are scanned per scan command. if scan request is issued by user during Tx traffic, radio will be out of channel for "4 * per_chan_scan_time" for each scan command and will not be able to receive Rx packets. This adds delay in data traffic. We can minimize it by reducing number of channels scanned per scan command in this scenario. We can not always scan 1 channel per scan command due to limitation of number of command buffers. So we add code to decide number of channels scanned per scan command in associated state.

If scan operation is started when Tx traffic is already running, driver locks Tx queue until it gets completed. With this logic there is a delay for Tx packets. This patch implements new approach to give Tx path higher priority in this case. Driver internally sends multiple synchronous scan commands to firmware when scan is requested by user. Now we will make sure that Tx queue is empty everytime before sending next scan command. If Tx queue isn't empty scan command will be postponsed by 20msec. This rule will be followed until Tx queue becomes empty or timeout of 1 second happens. In case of timeout scan operation will be aborted.

Currently the scan time per channel for active scanning is set to 200ms. It takes quite a while to finsh scanning on all channels, especially with a dual band configuration. Change the per channel scan time settings to the following values: passive scan: 110ms active scan: 30ms specific scan: 30ms Above settings have been tested on x86 and arm platforms.

The iwl-test flows were based on the cfg80211 testmode APIs. To remove this coupling, the op mode (during the initialization of the iwl_test object) is responsible to set the callbacks that should be used by iwl-test to allocate skbs for events and replies and to send events and replies. The current op modes implement these callbacks based on the cfg80211 testmode APIs.

When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys. The message is the log that was printed is: Queue 2 stuck for 10000ms This doesn't seem to fix the higher queues that get stuck from time to time.
