as "No L2CAP FCS option received" to CONF_RECV_NO_FCS which means
"Received L2CAP option NO_FCS". This flag really means that we have

In order to authenticate and configure an incoming SCO connection, the
BT_DEFER_SETUP option was added. This option is intended to defer reply
to Connect Request on SCO sockets.
When a connection is requested, the listening socket is unblocked but
the effective connection setup happens only on first recv. Any send
between accept and recv fails with -ENOTCONN.

The core specification defines 127 as the "not available" value (well,
"reserved" for BR/EDR and "not available" for LE - but essentially the
same). Therefore, instead of testing for 0 (which is in fact a valid
value) we should be using this invalid value to test if the tx_power is
available.

The move response command includes a result code indicating
"pending", "success", or "failure" status. A pending result is
received when the remote address is still setting up a physical link,
and will be followed by success or failure. On success, logical link
setup will proceed. On failure, the move is stopped. The receiver of
a move channel response must always follow up by sending a move
channel confirm command.

An L2CAP channel using high speed continues to be associated with a
BR/EDR l2cap_conn, while also tracking an additional hci_conn
(representing a physical link on a high speed controller) and hci_chan
(representing a logical link). There may only be one physical link
between two high speed controllers. Each physical link may contain
several logical links, with each logical link representing a channel
with specific quality of service.
During a channel move, the destination channel id, current move state,
and role (initiator vs. responder) are tracked and used by the channel
move state machine. The ident value associated with a move request
must also be stored in order to use it in later move responses.
The active channel is stored in local_amp_id.
