| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The background scan completion takes more time when the station is having heavy uplink traffic. The scan state machine decides to fall back to home channel on every off-channel visit when there are pending frames in tx queue. bgscan completion took ~30sec on dual band US regulatory card. scan period = (20 active channels * probe timeout) + (12 passive channels * passive probe timeout) + (32 * timeout on home channel) + (32 * flush timeout) Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

| * mac80211: Take into account TSF adjustment latency in Toffset setpointJavier Cardona2012-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | When testing mesh synchronization we observed a global TSF slowdown that was dependent on the number of synchronized mesh stations. This seems to be caused by the TSF adjustment (read/write) latency. Adding a small margin to the Toffset setpoint solved the problem.

| | | | | | | | | | | | | | | | | | | | | | Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL flag set. The ieee80211_check_queues() function always returns -EINVAL, preventing AP mode from starting. To fix this, check whether this flag is set before checking if cab_queue is set properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My grand plan to allow drivers to gradually move over to advertising virtual interface combinations and only enforce with drivers that do want it enforced doesn't seem to be working out, only Christian ever added the advertising (to carl9170), nobody else did. Begin enforcing combinations in cfg80211 so that users can rely on the information reported about a device. Cc: "Luis R.

| * NFC: The core part should generate the target indexSamuel Ortiz2012-04-12
| | | | | | | | | | | | | | | | | | | | | | | | The target index can be used by userspace to uniquely identify a target and thus should be kept unique, per NFC adapter. Moreover, some protocols do not provide a logical index when discovering new targets, so we have to generate one for them. For NCI or pn533 to fetch their logical index, we added a logical_idx field to the target structure. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W.

| * | batman-adv: skip the window protection test when the originator has no ↵Antonio Quartulli2012-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | neighbours When we receive an OGM from from a node for the first time, the last_real_seqno field of the orig_node structure has not been initialised yet. The value of this field is used to compute the current ogm-seqno window and therefore the protection mechanism will probably drop the packet due to an out-of-window error. To avoid this situation this patch adds a check to skip the window protection mechanism if no neighbour nodes have already been added. When the first neighbour node is added, the last_real_seqno field is initialised too. Reported-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org>
