Hi all,
This patchset adds support for the LE auto connection mechanism discussed
during the Wireless Summit in New Orleans.
The user configures the connection parameters and the auto connection
policy for each device according to the LE profiles that device supports.
The auto connection policies are:
* DISABLED: kernel never establishes connections autonomously.
* LINK_LOSS: kernel automatically reconnects if connection terminates due to
a link loss.
* ALWAYS: kernel always autonomously connects to device
In order to implement the auto connection mechanism, it was introduced the
background scanning infrastructure which keeps the controller (passively)
scanning as long as there is auto connection pending. Also, two new Mgmt
commands are introduced to add and remove connection parameters for a certain
device.
This patchset is organized as follows:
* Patch 1 - 3: Adds the new Mgmt commands.
* Patch 4 - 5: Use connection parameters specified by user.
* Patch 6: Introduce the background scan infrastructure.
* Patch 7 - 9: Implement the auto connection policies.
* Patch 10 - 11: Add special handling for devices that don't support scanning
and initiating connections at the same time.
* Patch 12 - 14: Add proper handling for auto connection and discovery running
at the same time.
* Patch 15: Add special handling for power off/on.
Regards,
Andre
