Hi Andre,
> This patch adds to hdev the connection parameters list (hdev->le_
> conn_params). The elements from this list (struct hci_conn_params)
> contains the connection parameters (for now, minimum and maximum
> connection interval) that should be used during the connection
> establishment.

> The struct hci_conn_params also defines the 'auto_connect' field
> which will be used to implement the auto connection mechanism.
>
> Moreover, this patch adds helper functions to manipulate hdev->le_
> conn_params list. Some of these functions are also declared in
> hci_core.h since they will be used outside hci_core.c in upcoming
> patches.

actually I would not include the auto_connect mode in the this stage of the patch set. We could have made more progress with this patch set and get things applied if things are not intermixed. So lets leave this out and only introduce it once we need it.
