[PATCH BlueZ 07/14] mgmt: Add LE scanning callback

[João Paulo Rechi Vita <jprvita@xxxxxxxxxxxxx>]

From: Claudio Takahasi <claudio.takahasi@xxxxxxxxxxxxx>

This patch adds a new callback to allow the adapter to control LE
scanning. The current approach uses the active scanning with default
windows and intervals defined by the core spec without any filtering.
