* wl12xx: disable 11a channels when wl->enable_11a is knownLuciano Coelho2010-12-151-6/+10
| | | | | | | | | | | | | | Disabling the 11a channels when not supported in the reg_notify function was not working as it should, because when the driver is initiailizing (and registering itself with mac80211), it would get the reg notification too early. At that point the driver wouldn't have received the NVS yet, so it wouldn't know whether 11a was supported. To fix this, we disable 11a channels when we read the NVS instead. Also, it is easier (and still safe) to set n_channels to zero instead of setting the disabled flag on every 11a channel. Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

* wl12xx: fix illegal memset if debugfs is not enabledLuciano Coelho2010-12-021-0/+3
| | | | | | | | | | If we try to reset the debugfs statistics when debugfs is not configured in the kernel, we're memset an illegal pointer, because it has never been allocated. So check whether we have debugfs enabled by looking into the wl->rootdir before trying to reset the fw_stats struct.

* wl1271: Fix setting of the hardware connection monitoring probe-req templateJuuso Oikarinen2010-11-265-13/+58
| | | | | | | | | | | | | | | The probe-request template used in the hardware connection monitoring feature thus far has been an empty one, without the SSID IE and without supported rate IEs. This causes problems with some AP's. Additionally, after connected scans, the template for connection maintenance would remain to be the one last used for scanning - potentially incorrect. Fix these by getting a pre-filled directed probe-request template for the associated-to AP from mac80211.

* wl12xx: disable 11a channels when regulatory changes if 11a is not supportedLuciano Coelho2010-11-261-1/+8
| | | | | | | | | | | | | Instead of simply not scanning for the 11a channels when not supported by the hardware, disable the channels in reg_notify. This centralizes the decision on whether to scan 5GHz channel in one place and allows userspace to know exactly which channels are in use. Based on Juuso Oikarinen's idea.

* wl12xx: Fix kernel crash related to hw recovery and interface shutdownJuuso Oikarinen2010-11-231-3/+9
| | | | | | | | | | | | | | It is possible that the op_remove_interface function is invoked exactly at the same time has hw recovery is started. In this case it is possible for the interface to be already removed in the op_remove_interface call, which currently leads to a kernel warning and a subsequent kernel crash. Fix this by ignoring the op_remove_interface call if the interface is already down at that point.

* wl12xx: Unset bssid filter, ssid and bssid from firmware on disassocJuuso Oikarinen2010-11-221-1/+4
| | | | | | | | | | | | | | | | | On the disassociation event from the mac80211, the wl12xx driver does not clear the chipset configuration related to the AP - i.e. it does not perform a DISCONNECT and then a JOIN with zero SSID and dummy BSSID. Also, it does not unset the BSSID filter. Often this is not a problem, as the above is performed upon entering idle state. But if a scenario arises where a new association is attempted without cycling through idle state, the new association will fail. Fix this by resetting the firmware state on disassociation.

| | | | | | | | | | | | | | | This adds generic functions for calculating Exponentially Weighted Moving Averages (EWMA). This implementation makes use of a structure which keeps the EWMA parameters and a scaled up internal representation to reduce rounding errors. The original idea for this implementation came from the rt2x00 driver (rt2x00link.c). I would like to use it in several places in the mac80211 and ath5k code and I hope it can be useful in many other places in the kernel code.

* mac80211: fix powersaving clients racesJohannes Berg2010-11-174-7/+29
| | | | | | | | | | | | | | | | | | | | | | The code to handle powersaving stations has a race: when the powersave flag is lifted from a station, we could transmit a packet that is being processed for TX at the same time right away, even if there are other frames queued for it. This would cause frame reordering. To fix this, lift the flag only under the appropriate lock that blocks TX. Additionally, the code to allow drivers to block a station while frames for it are on the HW queue is never re-enabled the station, so traffic would get stuck indefinitely. Fix this by clearing the flag for this appropriately. Finally, as an optimisation, don't do anything if the driver unblocks an already unblocked station.

* ath9k: store frame information used by aggregation inside the skb tx infoFelix Fietkau2010-11-172-109/+109
| | | | | | | | | | | | | | Since the pointers after the rates in the tx info cannot be used anymore after frames have been queued, this area can be used to store information that was previously stored in the ath_buf. With these changes, we can delay the ath_buf assignment in the aggregation code until aggregates are formed. That will not only make it possible to simplify DMA descriptor setup to do less rewriting of uncached memory, but will also make it easier to move aggregation out of the core of the ath9k tx path.
