Now that all accesses to the data_queue structures is done via the specialized rt2x00queue_get_tx_queue function or via direct accesses, there is no need for the rt2x00queue_get_queue function anymore, so remove it.

In the spirit of optimizing the code to get the queue structure of TX queues, also optimize the code to get beacon queues. We can simply use the bcn queue field of the rt2x00_dev structure instead of using the rt2x00queue_get_queue function.

The ATIM queue is considered to be a TX queue by the drivers that support the queue. Therefore include support for the ATIM queue to the rt2x00queue_get_tx_queue function so that the drivers that support the ATIM queue can also use that function. Add the support in such a way that drivers that do not support the ATIM queue are not penalized in their efficiency.

Current code for the atim queue is strange, as it is considered in the rt2x00_dev structure as a second beacon queue. Normalize this by letting the atim queue have its own struct data_queue pointer in the rt2x00_dev structure.

When setting up multiple BSSIDs in AP mode on an rt2800pci device we previously used the STAs AID to select an appropriate key slot. But since the AID is per VIF we can end up with two STAs having the same AID and thus using the same key index. This resulted in one STA overwriting the key information of another STA. Fix this by simply searching for the next unused entry in the pairwise key table. Also bring the key table init in sync with deleting keys by initializing the key table entries to 0 instead of 1.

ieee80211_get_tx_rate is not valid for HT rates. Hence, restructure the TX desciptor creation to be aware of MCS rates. The generic TX desciptor creation now cares about the rate_mode (CCK, OFDM, MCS, GF). As a result, ieee80211_get_tx_rate gets only called for legacy rates.

HT and no-HT rt2x00 devices use a partly different TX descriptor. Optimize the tx desciptor memory layout by putting the PLCP and HT substructs into a union and introduce a new driver flag to decide which TX desciptor format is used by the device. This saves us the expensive PLCP calculation fOr HT devices and the HT descriptor setup on no-HT devices.

Newer devices like rt2800* own a hardware sequence counter and thus don't need to use a software sequence counter at all. Add a new driver flag to shortcut the software sequence number generation on devices that don't need it. rt61pci, rt73usb and rt2800* seem to make use of a hw sequence counter while rt2400pci and rt2500* need to do it in software.

In some cases (tx path for example) we don't need to check for non-tx queues in rt2x00queue_get_queue. Hence, introduce a new method rt2x00queue_get_tx_queue that is only valid for tx queues and use it in places where only tx queues are valid. Furthermore, this new method is quite short and as such can be inlined to avoid the function call overhead. This only converts the txdone functions of drivers that don't use an ATIM queue and the generic tx path.

In addition it fails to setup max_rates in the ieee80211_hw struct, This behavior may be responsible for the problems noted in Bug 14168.

The interrupt of the wl12xx is a level interrupt in nature, since the interrupt line is not auto-reset. However, since resetting the interrupt requires bus transactions, this cannot be done from an interrupt context. Thus, requesting a level interrupt would require to disable the irq and re-enable it after the HW is acknowledged. Since we now request a threaded irq, this can also be done by specifying the IRQF_ONESHOT flag. Triggering on an edge can be problematic in some platforms, if the sampling frequency is not sufficient for detecting very frequent interrupts. In case an interrupt is missed, the driver will hang as the interrupt line will stay high until it is acknowledged by the driver, which will never happen. Fix this by requesting a level triggered interrupt, with the IRQF_ONESHOT flag.

To achieve maximal throughput, it is very important to react to interrupts as soon as possible. Currently the interrupt handler wakes up a worker for handling interrupts in process context. A cleaner and more efficient design would be to request a threaded interrupt handler. This handler's priority is very high, and can do blocking operations such as SDIO/SPI transactions. Some work can be deferred, mostly calls to mac80211 APIs (ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a different worker, we can keep the irq handler thread more I/O responsive. In addition, on multi-core systems the two threads can be scheduled on different cores, which will improve overall performance. The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was changed. For simplicity, always query the FW for more pending interrupts. Since there are relatively long bursts of interrupts, the extra FW status read overhead is negligible. In addition, this enables registering the IRQ handler with the ONESHOT option.

The SDIO bus is claimed and released for each SDIO transaction. In addition to the few CPU cycles it takes to claim and release the bus, it may also cause undesired side effects such as the MMC host stopping its internal clocks. Since only the wl12xx_sdio driver drives this SDIO card, it is safe to claim the SDIO host once (on power on), and release it only when turning the power off. This patch was inspired by Juuso Oikarinen's (juuso.oikarinen@nokia.com) patch "wl12xx: Change claiming of the (SDIO) bus".

On newer hardware revisions, there is no need to write the host's counter at the end of a RX transaction. The same applies to writing the number of packets at the end of a TX transaction. It is generally a good idea to avoid unnecessary SDIO/SPI transfers. Throughput and CPU usage are improved when avoiding these. Send the host's RX counter and the TX packet count only if needed, based on the hardware revision.
