With the upcoming hardware offload implementation, some devices will have a different maximum duration for the remain-on-channel command. Advertise the maximum duration in mac80211, and make mac80211 set it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This patch allows the pm-qos value to be user configurable by making it as a module parameter.This will help our customers to configure the pm-qos value according to the effect in throughput due to the DMA latency problem which was observed in Intel Pinetrail platforms. The tested value of '55' will be filled as the default pm-qos-value incase the user does not specifies pm-qos value as a module parameter. example usage: sudo modprobe ath9k pmqos=65 Cc: Senthilkumar Balasubramanian <Senthilkumar.Balasubramanian@Atheros.com> Signed-off-by: Mohammed Shafi Shajakhan <mshajakhan@atheros.com> Signed-off-by: John W.

The current EEPROM reading code has some layout assumptions that now turned out to be false with some newer versions of the EEPROM. Luckily, we can avoid all such assumptions by using data in the EEPROM itself, so implement using that. However, for risk mitigation purposes, keep the old reading code for current hardware for now.

Commit 6175ddf0 changes the way memcpy_toio() works for x86_64, causing firmware loading to fail for some Ralink WLAN devices with the rt2800pci driver since linux 2.6.34. This causes the log message: "phy0 -> rt2800pci_load_firmware: Error - PBF system register not ready.". Fix this by using __iowrite32_copy instead of memcpy_toio().

The Queue names were incorrectly copied from the legacy drivers, as a result the queue names were inversed to what was expected. This renames the queues using this mapping: QID_AC_BK -> QID_AC_VO (priority 0) QID_AC_BE -> QID_AC_VI (priority 1) QID_AC_VI -> QID_AC_BE (priority 2) QID_AC_VO -> QID_AC_BK (priority 3) Note that this was a naming problem only, which didn't affect the assignment of frames to their respective queues.

Add the rt2x00_dmastart function to rt2x00lib which marks the queue_entry as "owned by device", and increased the Q_INDEX number. This cleanups up the index handling by rt2x00lib which at until so far used hackish approaches to keep the RX queue index numbering sane.

Add wrapper functions in rt2x00queue.c to start & stop queues. This control must be protected using a mutex. Queues can also be paused which will halt the flow of packets between the driver and mac80211. This doesn't require a mutex protection.

As part of the queue refactoring, change the queue callback function names to have 3 different actions: start, kick & stop. We can now also remove the STATE_RADIO_RX_ON/STATE_RADIO_RX_OFF device_state flags, and replace the usage with using the start_queue/stop_queue callback functions. This streamlines the RX queue handling to the similar approach as all other queues.

As part of the queue refactoring, we now introduce 3 queue commands: start, kick, stop. - Start: will enable a queue, for TX this will not mean anything, while for beacons and RX this will update the registers to enable the queue. - Kick: This will kick all pending frames to the hardware. This is needed for the TX queue to push all frames to the HW after the queue has been started - Stop: This will stop the queue in the hardware, and cancel any pending work (So this doesn't mean the queue is empty after a stop!). Move all code from the drivers into the appropriate functions, and link those calls to the old rt2x00lib callback functions (we will fix this later when we refactor the queue control inside rt2x00lib).

Commit 02044643 "Check for specific changed flags when updating the erp config" changed the way in which a new beacon interval gets handled. However, due to a bug in rt2800usb and rt2800pci the beacon interval was reset during each scan, thus causing problems in AdHoc mode. Fix this by not cleaning up the beacon interval when killing the beacon queue but just prevent the device from sending out beacons.

Recent changes to the TX-done code of rt2x00 resulted in TX-ed frames not being returned to mac80211 in the original state, and therefore with insufficient headroom for re-transmissions. Fix this by reverting the changes done and by ensuring we remove the inserted L2pad by moving the header backwards instead of the data forwards. At the same time also make sure that the rt2x00queue_remove_l2pad will not move any memory when a frame has no data at all.
