the link manager runs on the chip and L2CAP is part of the host protocol
stack. And in between we have the HCI. As far as I know, the connection
handle from the link manager must not be the same connection handle used
on the HCI. Feel free to correct me, because I never really looked under
the HCI layer in that detail.
