| | * wl12xx: Enable beacon early termination in 2.4GHz band onlyShahar Levi2011-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Beacon early termination doesn't help much in the 5GHz band and masks channel switch IE Beacons. Thus, change the code to use BET only in 2.4GHz. [Reworded the commit log slightly -- Luca.] Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When rx_streaming.interval is non-zero, use automatic rx streaming. Enable rx streaming on the each rx/tx packet, and disable it rx_streaming.duration msecs later. When rx_streaming.always=0 (default), rx streaming is enabled only when there is a coex operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wl12xx supports the "rx streaming" feature: When in ps mode, and @timeout msecs have been passed since the last rx/tx, it issues trigger packets (QoS-null/PS-Poll packets, according to the ac type) in const intervals (in order to reduce the rx time).

* wl12xx: fix oops in sched_scan when forcing a passive scanLuciano Coelho2011-05-31
| | | | | | | | | | | | | | | | Fix kernel oops when trying to use passive scheduled scans. The reason was that in passive scans there are no SSIDs, so there was a NULL pointer dereference. To solve the problem, we now check the number of SSIDs provided in the sched_scan request and only access the list if there's one or more (ie. passive scan is not forced). We also force all the channels to be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally before the checks in the wl1271_scan_get_sched_scan_channels() function.

* wl12xx: add separate config value for DFS dwell time on sched scanLuciano Coelho2011-05-31
| | | | | | | | | | | | | Use a different value for DFS dwell time when performing a scheduled scan. Previously we were using the same value as for normal passive scans. This adds some flexibility between these two different types of passive scan. For now we use 150 TUs for DFS channel dwell time. This may need to be fine-tuned in the future.

* wl12xx: fix DFS channels handling in scheduled scanLuciano Coelho2011-05-31
| | | | | | | | | | | | | DFS channels were never getting included in the scheduled scans, because they always contain the passive flag as well and the call was asking for DFS and active channels. Fix this by ignoring the passive flag when collecting DFS channels. Also, move the DFS channels in the channel list before the 5GHz active channels (this was implemented in the FW differently than specified).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating as AP, the TX queues are not stopped when we start recovery. mac80211 is notified only after the fact. When there is pending TX, it will be queued even after the FW is down.
