I saw that when the watchdog triggers, the packets do go through if we wait enough time. So we still have an issue where packets are blocked in the Tx queue for a short while and this needs to be debugged separately. For now, don't restart the driver when it is not needed. Signed-off-by:

The dwell time for scanning is currently limited so that it fits into the timings inside the ucode when that is tracking DTIM/beacon periods for the AP(s) it's connected to. However, when it's connected to two APs, those may be in lockstep, for example if they both have a DTIM interval of 100 TU, then one could be 50 TU after the other, leaving only 50 TU free to be used by scanning. Since we can't know how far apart they are the only option is to restrict to 1/2 of the minium of the two APs. In theory, it would be possible to not use 1/2 of the minimum but take into account that if they have different intervals then there will be a bit more time since they can't be in lockstep, but as they will have 100 TU intervals in practice that complex calculation will probably just result in hard-to-find bugs.

Currently when mac80211 asks to change the interface type, we will accept it for both the BSS and PAN contexts. This is not terribly complicated today, but with the addition of the P2P Device abstraction the PAN context handling will get more complex, so restrict mac_change_interface to the BSS context. Also fix a small locking issue and use is_active instead of the vif pointer to check if the other context is activated, guarding exclusive interface types on the BSS context (IBSS) against the PAN context being used for something else.

When the first interface is active, then scanning on it or the second interface can take a little longer than 7s (I observed around 8s.) Bump the timeout to 15s to avoid aborting a scan that is still running, just taking more time. Reviewed-by:

My previous commit to shorten the radio reset time caused issues as the firmware checks the active dwell time against the quiet time, asserting that the dwell is >= quiet time. This isn't really needed in case of passive scanning like here, but of course we need to pass that check. To fix this, override the quiet time to be the same as the radio reset dwell time.

Now that the eeprom parsing code overrides the sku field directly with 11n_disable parameters, there's no longer a need to keep a copy of this field. Reviewed-by:

The effect of using a short single-channel scan to reset the radio is that scanning a channel that isn't in use needs to re-tune the radio. This means that the dwell time is irrelevant, so use a shorter time. While at it, clean up the code for this a bit. Reviewed-by:

My commit 26a7ca9a ("iwlwifi: refactor EEPROM reading/parsing") broke the 11n_disable module parameter's BIT(0) to disable all HT operation (using the other bits to disable aggregation only was unaffected). Restore this by overriding the SKU when parsing the EEPROM if the module parameter is set. Reported-by:

When the device is doing an internal radio reset scan, ROC can be rejected to the supplicant with busy status which confuses it. One option would be to queue the ROC and handle it later, but since the radio reset scan is very quick we can just wait for it to finish instead. Also add a warning since we shouldn't run into the case of having a scan active when requesting a ROC in any other case since mac80211 will not scan while ROC or ROC while scanning. Reviewed-by:

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:

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. Reviewed-by:
