C14 LE Client Identifier. Each LE Client requires a
LE Client Identifier (LECID) assigned by the LE
Server during the Join phase. The LECID is placed
in control requests by the LE Client and MAY be
used for echo suppression on multicast data frames
sent by that LE Client. This value MUST NOT
change without terminating the LE Client and
returning to the Initial state. A valid LECID
MUST be in the range X'0001' through X'FEFF'.
The value of this object is only meaningful for a LEC
that is connected to a LES. For a LEC which does not
belong to an emulated LAN, the value of this object
is defined to be 0.
