2010-03-09iwlwifi: change WEP key protection to use mutexJohannes Berg
For later station notification support we would like WEP key setting to be done synchronously always. Currently all places from which WEP key is set can sleep, but the usage of sta_lock prevents it to do so. Modify the locking to use priv->mutex instead and thus enable this call to sleep.

2010-03-09iwlagn: move sysfs flags and filter_flags files to debugfsJohannes Berg
These files are incompatible with some changes I'm making, and don't really belong into sysfs anyway as they can only be used for debugging. Since writing them will probably crash the firmware, keep only the reading part and move them into debugfs.

2010-03-09iwlwifi: remove STATUS_MODE_PENDINGJohannes Berg
Since rfkill integration, mac80211 can no longer add an interface while the hardware is not ready, so STATUS_MODE_PENDING can never be set. Also, remove another superfluous channel sanity check and return the commit_rxon return value in case it failed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-03-09iwlwifi: remove alive start adhoc restartJohannes Berg
This code will never trigger, because when we call this during interface start, neither priv->vif nor priv->iw_mode conditions will be true, and when it happens during reset then priv->vif is also NULL. Also, in both cases the same code will be executed as part of iwl_bss_info_changed(), which contains a copy of this code.

2010-03-09iwlwifi: move 3945 clip groups to 3945 dataJohannes Berg
Only used on 3945, so it can be in the 3945-specific part of the data. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-03-09iwlwifi: clear up AC/FIFO debug outputJohannes Berg
Not all queues are mapped for frame transmission, so saying "AC" is misleading. They are all mapped to FIFOs, obviously, though, so use that term and also say AC/CMD instead of just AC for the queue type.

2010-03-09iwlwifi: remove sanity checkJohannes Berg
iwl_mac_beacon_update can only be called when the operating mode is IBSS, so it doesn't need to verify that again. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-03-09iwlwifi: remove IBSS channel sanity checkJohannes Berg
mac80211 will always enforce using a channel that the driver allowed for IBSS use. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-03-09iwlwifi: remove priv->active_rate_basicJohannes Berg
This variable is assigned a default value, but then assigned zero as soon as mac80211 calls a change channel (which will happen right after the hw is started) and after that it never changes again.

2010-03-09iwlwifi: remove frame droppingJohannes Berg
With some of the new code in mac80211, public action frames can be exchanged as non-injected frames even while not associated. Aside from that, dropping frames here is pointless since we do deal with arbitrary frames that were injected already, so let mac80211 make the decision about which frames to allow or not.

2010-03-09iwlwifi: remove dead code from iwl_mac_reset_tsfJohannes Berg
iwl_mac_reset_tsf will only ever be called in IBSS mode, so checking for other modes is not useful and the code that depends on that will not be executed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

2010-03-09iwlagn: remove write-only variablesJohannes Berg
Updating the variables last_rx_rssi, last_tsf and last_beacon_time needs a lot of code but they are not actually used in iwlagn (only in 3945) so we can move them to the 3945 specific data.

2010-03-09iwlwifi: move ICT data to agn part of unionJohannes Berg

2010-03-09iwlwifi: move 3945 specific data into unionJohannes Berg
To be obviously correct, this patch only modifies 3945 files and the struct definition. A follow-up patch will create the AGN part of the union. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-03-09iwlagn: move ICT code into separate fileJohannes Berg
All the ICT ISR code is iwlagn specific, and doesn't need to be in iwlcore. So create a new iwl-agn.h header file that will hold agn specific function declarations etc., and move the ICT code into a new iwl-agn-ict.c file that is linked into iwlagn. This also gets rid of exporting those symbols. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

The AR_IMR_S2 register sometimes cannot be read correctly. Instead of a valid value, 0xdeadbeef is returned.
