| * mac80211: only cancel software-based scans on suspendJohn W. Linville2010-09-012-1/+8
| | | | | | | | | | | | | | | | | | Otherwise the hardware scan handler could access an invalid scan request structure. The driver should cancel any pending hardware scans during the suspend process anyway, so also add a warning if the hardware scan is still pending when the device resumes. Signed-off-by: John W.

| * mac80211: cancel scan in ieee80211_restart_hw if software scan pendingJohn W. Linville2010-08-311-1/+7
| | | | | | | | | | | | | | | | | | | | | | This function exists to clean-up after a hardware error or something similar. The restart is accomplished using the same infrastructure used to resume after a suspend. The suspend path cancels running scans, so it seems appropriate to do that here as well for software-based scans. If a hardware-based scan is pending, issue a warning message since this indicates that the drivers has failed to clean-up after itself. Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * rt2x00: Cleanup rt2x00usb_watchdog_reset_txIvo van Doorn2010-08-311-26/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rt2x00usb_watchdog_reset_tx performs the same task as rt2x00usb_kill_tx_queue, with the only difference is that it waits for all entries to be returned to the driver and for all frames the status has been reported to mac80211. We can easily split this task by calling rt2x00usb_kill_tx_queue, sleep for a short period and invoke the TX status reporting function. By adding the sleep() to the kill_entry we make sure that even during shutdown we guarentee the entry has been killed when the function returns. To make this work correctly the interrupt handlers have to be updated to prevent checking for the RADIO_ENABLED flag too early which prevents the ownership of the entry to be reset. Additionally a check for the DEVICE_PRESENT flag is not required but is nice to prevent race conditions when the device was unplugged. Additionally rather then calling rt2x00usb_work_txdone() for status reporting we let the driver perform the TX status reporting first. If this is not sufficient then rt2x00usb_work_txdone() will still be used to cleanup the mess.

| * rt2x00: Split watchdog check into a DMA and STATUS timeoutIvo van Doorn2010-08-316-14/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The watchdog for rt2800usb triggers frequently causing all URB's to be canceled often enough to interrupt the normal TX flow. More research indicated that not the URB upload to the USB host were hanging, but instead the TX status reports. To correctly detect what is going on, we introduce Q_INDEX_DMA_DONE which is an index counter between Q_INDEX_DONE and Q_INDEX and indicates if the frame has been transfered to the device. This also requires the rt2x00queue timeout functions to be updated to differentiate between a DMA timeout (time between Q_INDEX and Q_INDEX_DMA_DONE timeout) and a STATUS timeout (time between Q_INDEX_DMA_DONE and Q_INDEX_DONE timeout) All Q_INDEX_DMA_DONE code was taken from the RFC from Helmut Schaa <helmut.schaa@googlemail.com> for the implementation for watchdog for rt2800pci.

| | | | | | | | | | | | | | | | | | | | | | | | | | USB devices upload their beacon and then automatically send it out every beacon interval. However when killing a TX queue we only kill the URB and not the actual transmission of the beacon. This will reset the Beacon register to prevent any beacons from being transmitted.

| | | | | | | | | | | | | | | | | | | | | | | | | | According to the legacy drivers the AUTOWAKEUP_CFG register must be reset to 0 before loading the firmware. Instead of during rt2800{pci,usb}_write_firmware it must actually be done in rt2800_load_firmware() before resetting the WPDMA_GLO_CFG and PWR_PIN_CFG registers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of printing a warning when the PID, ACK, or WCID of an entry don't match the TX status report, we should skip the entry to search for the entry which actually does match the TX status data. This reduces the number of watchdog errors on the TX queues for rt2800usb, and seems to improve the reliability of the TX flow a bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ave_beacon_signal value uses 1/16 dB unit and as such, must be initialized with the signal level of the first Beacon frame multiplied by 16. This fixes an issue where the initial CQM events are reported incorrectly with a burst of events while the running average approaches the correct value after the incorrect initialization. This could cause user space -based roaming decision process to get quite confused at the moment when we would like to go through authentication and DHCP.

So while I was adding the state field I figured I could use it to fix it. The problem, as I understand it, is that when we go offchannel while the driver has a queue stopped, the driver will likely start draining the queue and then enable it while offchannel. This in turn will enable the interface queue, and that leads to transmitting data frames on the wrong channel. Fix this by keeping track of offchannel status per interface, and not enabling the interface queues on interfaces that are offchannel when the driver enables a queue.
