2011-01-31rt2x00: Convert rt2400pci interrupt handling to use taskletsHelmut Schaa1-39/+115
Fix interrupt processing on slow machines by using individual tasklets for each different device interrupt. This ensures that while a RX or TX status tasklet is scheduled only the according device interrupt is masked and other interrupts such as TBTT can still be processed. Also, this allows us to use tasklet_hi_schedule for TBTT processing which is required to not send out beacons with a wrong DTIM count (due to delayed periodic beacon updates). Furthermore, this improves the latency between the TBTT and sending out buffered multi- and broadcast traffic. As a nice bonus, the interrupt handling overhead should be much lower.

2011-01-31rt2x00: Limit beacon updates in bss_info_changed to USB devicesHelmut Schaa1-2/+3
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.

2011-01-31rt2x00: Refactor beacon code to make use of start- and stop_queueHelmut Schaa14-85/+185
This patch allows to dynamically remove beaconing interfaces without shutting beaconing down on all interfaces. The only place to start and stop beaconing are now the start- and stop_queue callbacks. Hence, we can remove some register writes during interface bring up (config_intf) and only write the correct sync mode to the register there. When multiple beaconing interfaces are present we should enable beaconing as soon as mac80211 enables beaconing on at least one of them. The beacon queue gets stopped when the last beaconing interface was stopped by mac80211. Therefore, introduce another interface counter to keep track ot the number of enabled beaconing interfaces and start or stop the beacon queue accordingly. To allow single interfaces to stop beaconing, add a new driver callback clear_beacon to clear a single interface's beacon without affecting the other interfaces. Don't overload the clear_entry callback for clearing beacons as that would introduce additional overhead (check for each TX queue) into the clear_entry callback which is used on the drivers TX/RX hotpaths. Furthermore, the write beacon callback doesn't need to enable beaconing anymore but since beaconing should be disabled while a new beacon is written or cleared we still disable beacon generation and enable it afterwards again in the driver specific callbacks. However, beacon related interrupts should not be disabled/enabled here, that's solely done from the start- and stop queue callbacks. It would be nice to stop the beacon queue just before the beacon update and enable it afterwards in rt2x00queue itself instead of the current implementation that relies on the driver doing the right thing. However, since start- and stop_queue are mutex protected we cannot use them for atomic beacon updates.
