* rt2x00: Don't overwrite beacon buffers in pairwise key setupHelmut Schaa2010-10-05
| | | | | | | | | | | | rt2800 devices use parts of the pariwise key table to store the beacon frames for beacon 6 and 7. To not overwrite the beacon frame buffers limit the number of entries we store in the pairwise key table to 222. Also add some descriptive comments about this shared memory usage.

* mac80211: Add validity check for beacon_crc valueJuuso Oikarinen2010-10-05
| | | | | | | | | | | | | | | | | | | | | On association to an AP, after receiving beacons, the beacon_crc value is set. The beacon_crc value is not reset in disassociation, but the BSS data may be expired at a later point. When associating again, it's possible that a beacon for the AP is not received, resulting in the beacon_ies to remain NULL. After association, further beacons will not update the beacon data, as the crc value of the beacon has not changed, and the beacon_crc still holds a value matching the beacon. The beacon_ies will remain forever null. One of the results of this is that WLAN power save cannot be entered, the STA will remain foreven in active mode. Fix this by adding a validation flag for the beacon_crc, which is cleared on association.

| | | | | | | | | | | | In the ath9k debugging feature 'wiphy' the current channel used by the station is incorrectly displayed.This is because the channels available are sequentially mapped from numbers 0 to 37.This mapping cannot be changed as the channel number is also used as an array index This fix solves the above problem by calculating the channel number from center frequency.

* carl9170: support firmware-based rx filterChristian Lamparter2010-10-05
| | | | | | | | | | | | | | | | | | | | | | The hardware rx-filter was essentially disabled, because of a serve, yet unidentifiable problem with iwlagn. Due to these circumstances the driver and mac80211 were left with the job of filtering. This is very unfortunate and has proven to be expensive in terms of latency, memory and load. Therefore the new 1.8.8.3 firmware introduces a flexible filtering infrastructure which allows the driver to offload some of the checks (FCS & PLCP crc check, RA match, control frame filter, etc...) whenever possible.

| * iwlwifi: send DC calib config to runtime ucodeShanyu Zhao2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since uCode is responsible for doing DC calibration, there's no need to let init uCode to do initial DC calibration then send results back to driver, then driver sends the results to runtime uCode. Driver can simply tell runtime uCode to do DC calibration. Actually, this patch does not disable DC calib for init uCode. It just prevent driver from saving and sending the DC calib results (from init ucode) to runtime uCode. The driver still uses 0xffffffff in CALIB_CFG_CMD for init ucode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iwlwifi driver supports multiple devices. Since some device needs special configuration we create a new iwl_nic_ops structure which is configurable per device. Currently there is only one function pointer inside this structure: additional_nic_config(). The iwl_nic_ops structure is added to the top level in struct iwl_ops, making it easier to change per device. Duplication of the iwl_lib_ops structure is no longer needed. With this new ops the previous function pointer set_calib_version is no longer needed since it is just a per device nic configuration. As part of the code restructuring, a bug is addressed. Indication of calib version to uCode is only needed for 6050 devices, however, current implementation set calib version for all 6000 devices for which DC calib is needed. To fix this, create iwl6050_ops for 6050 devices and only populate iwl_nic_ops in this structure. Signed-off-by: Shanyu Zhao <shanyu.zhao@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

This can be avoided by not calling scan_completed but abort_scan in iwl3945_request_scan in the done: branch of the function which is used as an error out. The done: branch seems to be an error-out branch, as, for example, if iwl_is_ready(priv) returns false the done: branch is executed. NOTE: I'm not familiar with the driver at all. I just quickly scanned as a reaction to https://bugzilla.kernel.org/show_bug.cgi?id=17722 the users of scan_completed in the iwl3945 driver and noted the odd discrepancy between the comment above this instance and the comment in mac80211 scan_completed function.

The wmm_last_param_set is initialized to -1 on association in order to ensure the configuration is made to the driver at least once on association, but currently this initialization is done *after* the WMM parameter configuration function was called. This leads to unreliability in the driver getting properly configured on first association (depending on what counter value the AP happens to use.) When disassociating (the wmm default parameters are configured to the driver) and then reassociating, due to the above the WMM configuration is not set to the driver at all. On drivers without beacon filtering the problem is corrected by later beacons, but on drivers with beacon filtering the WMM will remain permanently incorrectly configured. Fix this by moving the initialization of wmm_last_param_set to -1 before ieee80211_sta_wmm_params is called on association.
