2010-09-14rt2x00: Check for specific changed flags when updating the erp configHelmut Schaa11-181/+256
Previously rt2x00 was always updating all erp related config variables even though mac80211 might only have changed one. Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values. This fixes an issue in AP mode where the beacon interval is not initialized (and thus zero) but still sent to the hardware causing an interrupt storm on rt2800pci hanging the system.

2010-09-14rt2x00: Antenna diversity does not work in 2.6.35Lars Ericsson2-10/+6
The test if antenna diversity is at all enabled uses a local variable 'flags' to prepare the test condition, but uses 'ant->flags' when the test is evaluated. The effect is that the diversity evaluation will never start. I can see two solutions, use the 'flag' in the test condition or revert the local flag change. My attached patch took alternative two. Then the evaluation start but it will still not switch antenna. The problem is a code section in rt2x00lib_config_antenna (). The effect of that code section is that any change the diversity function perform will be effectively shorten and no antenna selection command issued. The attached patch will filter out any ANTENNA_SW_DIVERSITY setting but forward all other Signed-off-by: Lars Ericsson <lars_ericsson@telia.com> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2010-09-11iwlwifi: fix and describe iwl_adjust_beacon_intervalJohannes Berg2-4/+25
The iwl_adjust_beacon_interval function is a bit of black magic, so add comments to it describing what it does. Also, in the case when there's no beacon interval set, program the default into the device (instead of adjusting, which results in the max) since using the max in that case interacts badly with dual-mode/PAN parameters. Also update the PAN parameters accordingly and use the same constant as here. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

Since the starting rate is already the lowest one for a specific band it should be actually filled evenly with the starting rate: 1M and 6M for 5.2GHZ and 2.4GH respectively. The bug is that for for A or G-only it decreases to CCK rates which are not supported. iwl_get_prev_ieee_rate function is just not band aware.

2010-09-03iwlagn: open/close envlope to force move BT state machineWey-Yi Guy3-21/+31
In uCode, BT state machine need to receive open envlope command before perform calibration; followed by close envlope command to move to next stage. Since Linux has two separated uCode, one for init and the second one for runtime; we use open envlope commands for init uCode to indicate we are ready to perform calibration operation. But for runtime uCode, we are not doing any init calibration, so we issue open/close envlope commands to force uCode move to "BT COEX ON" state. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-09-01mac80211: only cancel software-based scans on suspendJohn W. Linville2-1/+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.

2010-08-31mac80211: cancel scan in ieee80211_restart_hw if software scan pendingJohn W. Linville1-1/+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>
2010-08-31rt2x00: Cleanup rt2x00usb_watchdog_reset_txIvo van Doorn1-26/+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.

2010-08-31rt2x00: Split watchdog check into a DMA and STATUS timeoutIvo van Doorn6-14/+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.

2010-08-31rt2x00: Correctly kill beacon queueIvo van Doorn3-3/+27
