2009-08-14mac80211: Move mpath and mpp growth to mesh workqueue.Javier Cardona
This prevents calling rcu_synchronize from within the tx path by moving the table growth code to the mesh workqueue. Move mesh_table_free and mesh_table_grow from mesh.c to mesh_pathtbl.c and declare them static. Also, re-enable mesh in Kconfig and update the configuration description.

2009-08-14mac80211: Assign a default mesh beaconing interval.Javier Cardona
The mesh stack was enabling beaconing without specifying an interval. This patch defines a default beaconing interval of 1s. Incidentally, this fixes mesh beaconing in mac80211_hwsim devices. Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-08-14mac80211: Early detection of broken mesh paths when using minstrel.Javier Cardona
This change triggers a path discovery as soon as the link quality degrades below a certain threshold. This results in a faster path recovery time than by simply relying on the periodic path refresh mechanism to detect broken links.

2009-08-14mac80211: Update the station failed frames average when minstrel is used.Javier Cardona

2009-08-14mac80211: Use 3-address format for mesh broadcast frames.Javier Cardona
The 11s task group recently changed the frame mesh multicast/broadcast frame format to use 3-address. This was done to avoid interactions with widely deployed lazy-WDS access points. This patch changes the format of group addressed frames, both mesh-originated and proxied, to use the data format defined in draft D2.08 and forward. The address fields used for group addressed frames is: In 802.11 header ToDS:0 FromDS:1 addr1: DA (broadcast/multicast address) addr2: TA addr3: Mesh SA In address extension header: addr4: SA (only present if frame was proxied) Note that this change breaks backward compatibility with earlier mesh stack versions.

2009-08-14ath5k: Use SWI to trigger calibrationNick Kossifidis
* Get rid of calibration timer, instead use a software interrupt to schedule the calibration tasklet. a) We don't need a timer for this, there is no need for accuracy even with round_jiffies i think this is a waste of resources. Also we don't need to run calibration if we are idle (no interrupts). b) When we add ANI support we 'll just extend the poll function and calibration tasklet and handle all periodic phy calibration on one place (much cleaner). c) Having calibration on a tasklet is better since during calibration we can't transmit or receive (antennas are detached to measure noise floor), previously calibration could run in parallel with tx/rx and interfere (packet loss). v2: kill tasklet on stop_hw, stop/wake queues v3: use time_is_before_eq_jiffies to compare timestamp with current time Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2009-08-14rt2x00: Fix beacon de-synchronization while update beaconIgor Perminov
When beacon is being updated to refresh TIM (AP mode), beacon frames are de-synchronizing (i.e. two neighbor beacon frames - before and after update - are being transmitted with a wrong time interval).

2009-08-14rt2x00: Fix for race condition while update beaconIgor Perminov
The patch "Implement set_tim callback for all drivers" can cause kernel oops in rt73usb_write_beacon. The oops is caused by one of the following race conditions: * In case of two near calls to set_tim: rt2x00lib_beacondone_iter is cleaning the beacon skb, whereas rt73usb_write_beacon is still using it. * In case of two near updates of beacon: first as the result of set_tim and second as the result of a call from an application (e.g. hostapd). This patch fixes the race condition by rearranging the update logic and guarding rt2x00_intf->beacon->skb with a mutex.

2009-08-14iwlwifi: automatically adjust sleep levelJohannes Berg
Depending on required latency requested by pm_qos (via mac80211) we can automatically adjust the sleep state. Also, mac80211 has a user-visible dynamic sleep feature where we are supposed to stay awake after sending/receiving frames to better receive response frames to our packets, this can be integrated into the sleep command. Currently, and this patch doesn't change that yet, we default to using sleep level 1 if PS is enabled. With a module parameter to iwlcore, automatic adjustment to changing network latency requirements can be enabled -- this isn't yet the default due to requiring more testing. The goal is to enable automatic adjustment and then go into the deepest possible sleep state possible depending on the networking latency requirements. This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS to avoid the double-timer (one in software and one in the device) when transmitting -- the exact timeout may be ignored but that is not of big concern. Note also that we keep the hard-coded power indices around for thermal throttling -- the specification of that calls for using the specified power levels. Those can also be selected in debugfs to allow easier testing of such parameters.

2009-08-14iwlwifi: revert uCode Alive notification with timeoutReinette Chatre
commit "iwlwifi: uCode Alive notification with timeout" introduced a more reliable mechanism for ucode loading. Unfortunately we hit a problem with it frequently enough to make a 4965 unusable. The problem can be seen in debug log below. What this code attempts is to set runtime ucode up to load, start a timer to wait for the alive response from runtime ucode, and if it times out it tries again. As can be seen below we receive the alive response and wake the waiting task _before_ the tasks starts waiting. The task thus times out as the alive response is not received while it is waiting for it and it restarts the device. This starts the cycle all over again.

2009-08-14iwlwifi: Traffic type and counter for debugFsWey-Yi Guy
Break down the traffic type and counter for both Tx and Rx. Enhance the tx_statistics and rx_statistics debugfs function and move to /sys/kernel/debug/ieee80211/phy0/iwlagn/debug directory to help better debugging both driver and uCode related problems.

2009-08-14iwlwifi: new debugging feature for dumping data trafficWey-Yi Guy
The traffic buffer will only beallocated and used if either bit 23 (IWL_DX_TX) or bit 24 (IWL_DL_RX) of "debug" is set; example: "debug=0x800000" - log tx data traffic "debug=0x1000000" - log rx data traffic "debug=0x1800000" - log both tx and rx traffic The traffic log will store the beginning portion (64 bytes) of the latest 256 of tx and rx packets in the round-robbin buffer for debugging, user can examine the log through debugfs file. How to display the current logged tx/rx traffic and txfifo and rxfifo read/write point: "cat traffic_log" in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug directory By echo "0" to traffic_log file will empty the traffic log buffer and reset both tx and rx taffic log index to 0.

2009-08-14iwlwifi: re-introduce per device debuggingReinette Chatre
Commit "iwlwifi: make debug level more user friendly" cleaned up the debug level handling. In doing so it created a single global debug level for all devices. Some setups do consits of more that one iwlwifi device and in these setups there is a requirement that debug levels should be unique per device. We now re-introduce the per device debugging while maintaining the cleanup effort of the previous patch. The maintain the global debug level and now introduce a per-device debug level that will be used if it (the per-device debug level) is set. The per-device debug level can be controlled via the debug_level sysfs file while the global debug level is controlled by the debug module parameter.

This patch implements a basic rfkill support for p54 hardware and removes a rfkill related WARNING: fwio.c: In function ‘p54_setup_mac’: fwio.c:323: warning: ‘radio_enabled’ is deprecated. by abandoning radio_enable in flavour for IEEE80211_CONF_CHANGE_IDLE.
