2011-03-04rt2x00: Remove unused rt2x00queue_get_queue function.Gertjan van Wingerde2-27/+0
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.

2011-03-04rt2x00: Optimize getting the beacon queue structure.Gertjan van Wingerde2-2/+2
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.

2011-03-04rt2x00: Include ATIM queue support in rt2x00queue_get_tx_queue.Gertjan van Wingerde4-6/+9
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.

2011-03-04rt2x00: Fix rt2800 key assignment in multi bssid setupsHelmut Schaa1-13/+30
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.

2011-03-04rt2x00: Optimize TX descriptor handlingHelmut Schaa12-55/+79
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.

2011-03-04rt2x00: Optimize calls to rt2x00queue_get_queueHelmut Schaa6-8/+25
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.

2011-02-25mac80211: make tx() operation return voidJohannes Berg2-4/+3
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

Currently there are two places that trigger a beacon update on PCI devices. The bss_info_changed callback and the periodic update triggered by the TBTT or PRETBTT interrupt. Since the next TBTT or PRETBTT interrupt will periodically fetch an updated beacon remove the update_beacon call in the bss_info_changed callback for PCI devices. In the worst case it will take one beacon interval longer to fetch the new beacon then before. For devices that have a PRETBTT interrupt there should be no change at all.
