This can be used to implement offloaded rssi
threshold, beacon miss or even automatic
in-firmware BSS roaming in the future.

* [PATCH 2/2] ath10k: add hw connection monitor support

Some firmware revisions (e.g. qca6174 with fw73)
don't deliver beacons to host reliably. This
causes random disconnects even in perfect
conditions. This is most visible with
multi-channel operation.
All available firmware revisions seem to support
beacon miss offloading so there shouldn't be any
problems.

From: Michal Kazior @ 2015-03-09 13:36 UTC (permalink / raw)
To: ath10k; +Cc: linux-wireless, Michal Kazior
This can be used to implement offloaded rssi
threshold, beacon miss or even automatic
in-firmware BSS roaming in the future.

* [PATCH v2 2/2] ath10k: add hw connection monitor support
2015-03-09 13:36 ` Michal Kazior
@ 2015-03-09 13:36 ` Michal Kazior
-1 siblings, 0 replies; 16+ messages in thread
From: Michal Kazior @ 2015-03-09 13:36 UTC (permalink / raw)
To: ath10k; +Cc: linux-wireless, Michal Kazior
Some firmware revisions (e.g. qca6174 with fw73)
don't deliver beacons to host reliably. This
causes random disconnects even in perfect
conditions. This is most visible with
multi-channel operation.
All available firmware revisions seem to support
beacon miss offloading so there shouldn't be any
problems.

* conflict resolution hint: base of this patchset
(af695a659c69d347948ceab2c562e208ba48b26e) doesn't
include `ath10k: fix patching mistake for AP/IBSS CSA`
yet. Whichever you apply first you'll end up with a
conflict in ath10k_bss_disassoc(). Eventually the
data_lock goes away from there.

* [PATCH v2 2/2] ath10k: add hw connection monitor support
@ 2015-03-09 13:36 ` Michal Kazior
0 siblings, 0 replies; 16+ messages in thread
From: Michal Kazior @ 2015-03-09 13:36 UTC (permalink / raw)
To: ath10k; +Cc: linux-wireless, Michal Kazior
Some firmware revisions (e.g. qca6174 with fw73)
don't deliver beacons to host reliably. This
causes random disconnects even in perfect
conditions. This is most visible with
multi-channel operation.
All available firmware revisions seem to support
beacon miss offloading so there shouldn't be any
problems.

Notes:
v2:
* conflict resolution hint: base of this patchset
(af695a659c69d347948ceab2c562e208ba48b26e) doesn't
include `ath10k: fix patching mistake for AP/IBSS CSA`
yet. Whichever you apply first you'll end up with a
conflict in ath10k_bss_disassoc(). Eventually the
data_lock goes away from there.
