We currently stop the queue when changing the rate control between 20/40 MHz in the BSS. This seems to have been necessary when we actually changed the channel, but now that we just update the station it doesn't seem right any more. Remove it. Signed-off-by:

The channel type argument to the rate_update() callback isn't really the correct way to give the rate control algorithm about the desired RX bandwidth of the peer. Remove this argument, and instead update the STA capabilities with 20/40 appropriately. The SMPS update done by this callback works in the same way, so this makes the callback cleaner. Signed-off-by:

Changing the channel type during operation is confusing to some drivers and will be hard to handle in multi-channel scenarios. Instead of changing the channel, set it to the right HT channel before authenticating/associating and don't change it -- just update the 20/40 MHz restrictions in rate control as needed when changed by the AP. This also fixes a problem that Paul missed in his fix for the "regulatory makes us deaf" issue -- when we couldn't use 40 MHz we still associated saying we were using 40 MHz, which could in similarly broken APs make us never even connect successfully.

IEEE80211_MAX_QUEUES is an internal mac80211 value, it is not guaranteed to be always 4. The firmware API in mwifiex almost certainly doesn't care about mac80211 changing though, so mwifiex shouldn't use this value. Maybe it should use IEEE80211_NUM_ACS instead and that is what I'm doing here as at least that value will probably never change, but maybe it should have its own define instead. Signed-off-by:

Not all devices are really capable of implementing remain-on-channel, even if it is implemented in SW, as they can't necessarily deal with channel changes while associated. Remove the WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL and add it only if either the driver has remain_on_channel implemented in the driver/device. Also add it to all drivers that advertise P2P right now since those definitely have to have it working. Signed-off-by:

In https://bugzilla.kernel.org/show_bug.cgi?id=42976, a system with driver rtl8192se used as an AP suffers from "Out of SW-IOMMU space" errors. These are caused by the DMA buffers used for beacons never being unmapped. This bug was also reported at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/961618Reported-and-Tested-by:

This variable holds the ucode currently running on the device; which is determined by op_mode, so move this parameter there. Also, the name of the variable is a bit misleading, so rename it to cur_ucode. Signed-off-by:

Error log reporting does not belong to the transport layer, but to the op_mode loading the ucode, as it is the entity which knows about the ucode loaded, and what the error information means. Move device logging pointers from the transport layer to op_mode. With this change, transport layer only reports an error to the op_mode, which will figure out what to do with the error. This causes the driver to now dump out error logs when the command queue is stuck as well. Also, move the debugfs entry for event logs out of the transport layer and into op_mode. Signed-off-by:

The queue mapping is not only dynamic, it is also dependent on the uCode, as we can already see today with the dual-mode and non-dual-mode being different. Move the queue mapping out of the transport layer and let the higher layer manage it. Part of the transport configuration is how to set up the queues. Signed-off-by:

As idle is just a deep powersave mode for the device, it will easily scan while idle since that turns off powersave. This reduces the number of commands sent to the device when scanning. Signed-off-by:

The calibration results all come in while we're waiting for the calibration complete notification. As a consequence, there's no need to install a global RX handler for them, we can use the newly extended notification wait framework for this and make the code easier to follow. It is now quite explicit that we are processing the calibration results while waiting for the complete notification, before this was implicit and developers had to know this to understand why we wait for the calibration complete notification and what happens while we wait.

Sometimes, for example when we ask the uCode for calibration, we wait for the "complete" response while we also need the results that are sent in other, interim, notifications. Currently we handle this by installing an RX handler globally, but that isn't needed as this is the only time we want to use these notifications. So in order to be able to simplify at least future code that does the same, extend the notification wait framework to allow you to wait for multiple commands and decide based on the command whether the wait finished. While at it, also fix a race that can then become relevant -- if the wait function has returned true once it shouldn't be called again, today this can happen due to races between the triggering and the wakeup.

The flow handler (hardware) can put multiple frames into a single RX buffer. To handle this, walk the RX buffer and check if there are multiple valid packets in it. To let the upper layer handle this correctly introduce rxb_offset() which is needed when we pass pages to mac80211 -- we need to know the offset into the page there. Also change the page handling scheme to use refcounting. Anyone who needs a page will "steal" it, which marks it as having been used & refcounts it. The RX handler then has to free its own reference and must not reuse the page. Finally, do not set the bit asking the FH to give us each packet in a single buffer. This really enables the feature.
