[PATCH BlueZ 1/8] Add link_type information to the mgmt "Device Connected" event

[Vinicius Costa Gomes <vinicius.gomes@openbossa.org>]

In the case of incomming connections we have to know the type of
the device that connected to us.

Through hciops we have the LE Connection Complete event, that
information was lost when Management interface was being used.

The documentation is updated to reflect this.
