2010-03-10iwmc3200wifi: remove "_safe" for some list_for_each_entry usageZhu Yi
Use list_for_each_entry instead of list_for_each_entry_safe in places iteration against list entry removal is not required. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-03-10iwmc3200wifi: refuse to associate on unallowed channelsZhu Yi
We need to make sure we don't associate with APs on unallowed channels (according to regulatory setting). This could happen when the channel is not specified (auto-select) within the connection request. In this case we get the AP's channel until the firmware indicates the association succeeded later. We need to verify the associated channel. If the channel is disabled by regulatory, we have to disassociate with the AP. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

2010-03-09iwl3945: check ucode load error codeAbhijeet Kolekar
Check successful completion of BSM loading. Give a chance to load BSM again. If BSM loading is unsuccessful we should exit and not initilize NIC. Before this checking even if the BSM loading failed driver tries to initilize the NIC which should not be the case.

2010-03-09iwlwifi: clean up queue/fifo handlingJohannes Berg
4965 hardware has 7 queues reserved and the remaining ones used for aggregation, 5000 and higher need to have 10 reserved. This is not very clear in the code right now, unfortunately. Introduce a new IWL_TX_FIFO_UNUSED constant and make the queue/FIFO mapping arrays able to hold that value, and change the setup code to reserve all queues in the arrays (the queue number is the index) and use the new unused constant to not map those queues to any FIFO. Additionally, clear up the AC/queue mapping code to be more understandable. The mapping is the identity mapping right now, but with the mapping function I think it's easier to understand what happens there. Finally, HCCA isn't implemented at all and I think newer microcode removed it, so let's remove all mention of it in the code, some comments remain for 4965.

iwl_apm_stop_master and iwl_internal_short_hw_scan are only used within iwlcore and thus do not need to be exported. Reported-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
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.

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: clear up AC/FIFO debug outputJohannes Berg
Not all queues are mapped for frame transmission, so saying "AC" is misleading.

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

2010-03-09iwlagn: remove write-only variablesJohannes Berg

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.
