Bluetooth: Add support for BT_PKT_STATUS CMSG data for SCO connections
This change adds support for reporting the BT_PKT_STATUS to the socket CMSG data to allow the implementation of a packet loss correction on erroneous data received on the SCO socket. The patch was partially developed by Marcel Holtmann and validated by Hsin-yu Chao. Signed-off-by: Alain Michaud <alainm@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
