The authentication and association handshake already happens in the context of the new BSS, and the basic rates are needed at least for the ACK response frame to the authentication or association response frames. Therefore the basic rates should already be configured into the driver when those frames are sent. Change the logic to set up the basic rates in the connection preparation that happens for authentication and association (if needed). Signed-off-by:

As associating is possible without first authenticating (for FT over DS) association also has to be able to switch to the right channel, insert the station entry etc. Factor out this common code into a new function called ieee80211_prep_connection(). Signed-off-by:

Instead of setting assoc_data->wmm_used solely based on the BSS also take into account our own capabilities and later check those. Also rename "wmm_used" and "uapsd_used" to just "wmm" and "uapsd". Signed-off-by:

Change iwl_fw struct to hold an array of fw_img instead of three separated instances. Change fw_img to hold an array of fw_desc instead of two separate descriptors for instructions and data. Change load_given_ucode, load_section, verification functions etc. to support this structure. Signed-off-by:

Changed iwl_firmware_pieces structure to support an array of separate images, and an array of sections for each image. In fw_sec and fw_desc structures, added a field for offset from the HW address, to support 16.0 uCode that provides an offset instead of any other data about the section. This field is filled with default values when parsing instruction or data section. Signed-off-by:

Remove IWL_UCODE_NONE from enum iwl_ucode_type which, by being the default value in 0-initialized memory, implicitly allowed us to track whether any uCode had ever been loaded successfully (which would have been the INIT uCode) and instead explicitly track whether or not INIT uCode has been run.

This wait queue really belongs to the transport layer, as it is used for sending synchronous commands to the HW. However, only op_mode knows about errors and exceptional conditions, so make this queue accessible by the op_mode. Signed-off-by:

Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround warning with a statistics notification, this means we can't just remove it as we'd hoped. Abstract it out so that the higher layer can configure this as a kind of "filter" in the transport.

rt2800pci is suffering from beacon skew in AP mode. Some powersaving clients (like VOIP phones) are getting into trouble after some time when the beacon skew is getting too big. The ralink legacy drivers contain a function that indicates that the beacon timer is off by 1us per tbtt. And this function works around that by reducing the beacon interval for every 64th beacon transmission by 64us (the smallest possible value). Do the same in rt2800pci. This allows proper powersaving when rt2800pci is used in AP mode. Signed-off-by:

Disable multi stream rates (MCS > 7) when a STA is in static SMPS mode since it has only one active rx chain. Hence, it doesn't even make sense to sample multi stream rates. Signed-off-by:

As we've discussed, we want to avoid channel changes while associated. While the part when we actually associate needs a bit more work, the bit that happens on disassociating can be changed quite easily. Move the channel type change later in the disassociate process to set the channel only after the driver was told that it's now disassociated. As the driver could expect powersave to be enabled only when associated, this thus results in splitting the config call, but overall what happens makes more sense this way. Signed-off-by:

While setting up or tearing down a BA session mac80211 is buffering pending frames for the according TID. However, there's currently no limit on how many frames are buffered possibly leading to an out-of- memory situation. This can happen on systems with little memory when the CPU is fully loaded since the BA session work is executed in process context while frames can still come via softirq. Apply a limitation to the TIDs pending queue to avoid consuming too much memory in this situation. Signed-off-by:

in iwlwifi: move setting up fw parameters Meenakshi moved code up to configure the transport layer, but this code read the sku before it was set (from the EEPROM). This killed P2P. Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read. We need to reconfigure the transport in case the EEPROM disabled PAN support. This is not the nicest thing to do, but we have no choice. Document that we are allowed to configure the transport several times before start_fw, but not after. Signed-off-by:

With the mac80211 deauth sequence changes, the station is deleted before the device is set unassociated. This can cause the device to get confused as it expects the station to be there while the associated bit is set. To fix this, do not delete the AP station from the device when mac80211 asks for deletion, instead just mark it as unused and rely on the unassociated RXON to drop it from the station database in the device.
