2012-03-12ath9k: configure bss info at assoc notificationRajkumar Manoharan1-1/+1
The proper place to configure bss info is at assoc notification. So that ath9k continues to work if the supirous bssid notification will be removed in future.

2012-03-12rt2x00: Fix beacon skew in rt2800pciHelmut Schaa2-0/+33
rt2800pci is suffering from beacon skew in AP mode. Some powersaving clients (like VOIP phones) are getting into trouble after some time when the beacon skew is getting too big. The ralink legacy drivers contain a function that indicates that the beacon timer is off by 1us per tbtt. And this function works around that by reducing the beacon interval for every 64th beacon transmission by 64us (the smallest possible value). Do the same in rt2800pci. This allows proper powersaving when rt2800pci is used in AP mode. Signed-off-by: Helmut Schaa <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2012-03-09iwlwifi: restore PAN supportEmmanuel Grumbach2-30/+32
in iwlwifi: move setting up fw parameters Meenakshi moved code up to configure the transport layer, but this code read the sku before it was set (from the EEPROM). This killed P2P. Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read. We need to reconfigure the transport in case the EEPROM disabled PAN support. This is not the nicest thing to do, but we have no choice. Document that we are allowed to configure the transport several times before start_fw, but not after.

2012-03-08iwlwifi: don't delete AP station directlyJohannes Berg3-6/+53
With the mac80211 deauth sequence changes, the station is deleted before the device is set unassociated. This can cause the device to get confused as it expects the station to be there while the associated bit is set. To fix this, do not delete the AP station from the device when mac80211 asks for deletion, instead just mark it as unused and rely on the unassociated RXON to drop it from the station database in the device.

2012-03-08iwlwifi: redesign PASSIVE_NO_RX workaroundJohannes Berg11-119/+56
The PASSIVE_NO_RX workaround currently crosses through the op_mode and transport layers, which is a bit odd. This also isn't necessary, if the transport simply reports when queues are full (or no longer full) the op_mode can keep track of this state, and report to mac80211 only what *it* thinks is appropriate. What is appropriate can then be based on whether queues should be stopped to wait for RX or not. This significantly simplifies the transport API, it no longer needs to expose anything to stop a queue, nor to wake "any" queue, this can all be handled in the upper layer completely. Also simplify the handling to not be dependent on the context, that makes little sense as the queues are shared and both contexts have to be on the same channel anyway.
