2010-05-13iwlwifi: enable remaining 6000 Gen2 devicesShanyu Zhao
This patch enables all remaining 6000 series Gen2 devices. To work-around a firmware crash problem, we disable sending bt coex command for 6000g2b series devices.

2010-05-13iwlwifi: fix and add missing sta_lock usageReinette Chatre
There are a few places where sta_lock is used, but the station information protected by it is accessed outside of the lock. Address this in two ways, if the access won't sleep then just move the access into the lock, if the access can sleep then copy the needed station information to the stack to be accessed without risk of it changing while access in progress. Additionally, a number of other places access station station information without holding the sta_lock, fix those as well.

2010-05-12mac80211: add offload channel switch supportJohannes Berg
This adds support for offloading the channel switch operation to devices that support such, typically by having specific firmware API for it. The reasons for this could be that the firmware provides better timing or that regulatory enforcement done by the device requires special handling of CSAs. In order to allow drivers to specify the timing to the device, the new channel_switch callback will pass through the received frame's mactime, where available.

2010-05-11ath5k: drop warning on jumbo framesLuis R. Rodriguez
Jumbo frames are not supported, and if they are seen it is likely a bogus frame so just silently discard them instead of warning on them all time. Also, instead of dropping them immediately though move the check *after* we check for all sort of frame errors. This should enable us to discard these frames if the hardware picks other bogus items first. Lets see if we still get those jumbo counters increasing still with this. Jumbo frames would happen if we tell hardware we can support a small 802.11 chunks of DMA'd frame, hardware would split RX'd frames into parts and we'd have to reconstruct them in software. This is done with USB due to the bulk size but with ath5k we already provide a good limit to hardware and this should not be happening. This is reported quite often and if it fills the logs then this needs to be addressed and to avoid spurious reports. Cc: stable@kernel.org Signed-off-by: Luis R.

Remove iwl_get_sta_id() and use iwl_sta_id() instead as appropriate. This reduces the amount of code needed to find the right station significantly, and works since mac80211 passes the station only after it has been fully initialised, ie. even if TX races with station addition it will only be passed to TX once the addition is complete.

2010-05-10iwlagn: work around rate scaling reset delayReinette Chatre
When station is using an HT channel to communicate to AP and communication is lost then driver will first be notified that channel is not an HT channel anymore before AP station is removed. A consequence of that is that the driver will know that it is not communicating on HT anymore, but the rate scaling table is still under the impression it is operating in HT. Any time after driver has been notified channel is not HT anymore there will thus be a firmware SYSASSERT when the current active LQ command is sent. A workaround for this issue is to not send a LQ command in the short time between being notified channel is not HT anymore and rate scaling table being updated.
