The generic rt2x00 code has been changed to allow the drivers toimplement dynamic data_queue initialization. Remove the static data queue descriptor structures and implement the queue_init callback instead. The actual chipset is already known when the callback is used. This allows us to use a single callback for all supported devices.

2013-06-12rt2x00: add queue_init callback to rt2x00_opsGabor Juhos
The driver uses static data structures for initializing specific fields of a given data queue. These static queue data descriptor structures are containing values which related to a given chipset. Even though the values are chip specific, the actual selection of the used structure is based on device specific vendor/product identifiers. This approach works, but it is not always reliable. Sometimes the vendor and/or device IDs of the PCI and USB devices contains improper values which makes it impossible to select the correct structure for such devices. The patch adds a new callback to tr2x00_ops which is called after the chipset detection is finished. This allows the drivers to do dynamic initialization of the data_queue structure for a given queue based on the actual chipset. After each driver implements the queue_init callback, the data_queue_desc structure will be removed.

2013-06-12rt2x00: rt2x00queue: setup queue->threshold from queue->limitGabor Juhos
Use the queue->limit value instead of the qdesc->entry_num to compute the threshold. The two source values are the same and the data queue descriptor structure will be removed by a later patch. Also separate the computation from the rest of the init code to make further changes easier.

2013-06-12rt2x00: rt2x00dev: use rt2x00dev->bcn->limitGabor Juhos
The beacon data queue is initialized already, so fetch the number of the queue entries from that instead of using the entry_num field of the data queue descriptor. The two values are the same, and the use of the rt2x00dev->bcn->limit value allows us to get rid of a superfluous pointer dereference.

Add a new field into struct data_queue and store the size of the per-queue_entry private data in that. Additionally, use the new field in the rt2x00queue_alloc_entries function to compute the size of the queue entries for a given queue. The patch does not change the current behaviour but makes it possible to remove the queue_desc parameter of the rt2x00queue_alloc_entries function. That will be done by a subsequent patch.

2013-06-12rt2800: fix RT5390 & RT3290 TX power settings regressionStanislaw Gruszka
My change: commit cee2c7315f60beeff6137ee59e99acc77d636eeb Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Fri Oct 5 13:44:09 2012 +0200 rt2800: use BBP_R1 for setting tx power unfortunately does not work well with RT5390 and RT3290 chips as they require different temperature compensation TX power settings (TSSI tuning). Since that commit make wireless connection very unstable on those chips, restore previous behavior to fix regression. Once we implement proper TSSI tuning on 5390/3290 we can restore back setting TX power by BBP_R1 register for those chips.

2013-06-10rt2x00: rt2x00queue: initialize data_queue fields earlierGabor Juhos
Support for rt2800 device is broken since my 'rt2x00: rt2x00dev: use rt2x00dev->tx->limit' patch. The changelog of that commit says that the TX data queue is initialized already when the rt2x00lib_probe_hw() function is called. However as Jakub noticed it, this statement is not correct. The queue->limit field is initialized in the rt2x00queue_alloc_entries routine and that is not yet called when rt2x00lib_probe_hw() runs. Because the value of tx->limit contains zero, the driver tries to allocate a kernel fifo with zero size and kfifo_alloc rejects that with -EINVAL. PCI: Enabling device 0000:01:00.0 (0000 -> 0002) ieee80211 phy1: rt2x00_set_rt: Info - RT chipset 3071, rev 021c detected ieee80211 phy1: rt2x00_set_rf: Info - RF chipset 0008 detected ieee80211 phy1: rt2x00lib_probe_dev: Error - Failed to initialize hw rt2800pci: probe of 0000:01:00.0 failed with error -22 Move the data_queue field initialization from the rt2x00queue_alloc_entries routine into the rt2x00queue_init function. The initialization code is not strictly related to the allocation, and the change ensures that the queue_data fields can be used in the probe routines. The patch also introduces a helper function in order to be able to get the correct data_queue_desc structure for a given queue. This helper is only needed temporarily and it will be removed later.
