sapEthernetLLFAdminStatus specifies whether or not Link-
Loss Forwarding is enabled ('up'). When this object is set
to 'up' the underlying port will be forced into the
operationally 'down' state if the service is operationally
'down', or any of the 'sdpBindPwPeerStatusBits' are set,
and will set the underlying port's
tmnxPortEtherReasonDownFlags 'linklossFwd' bit. Setting
this object to 'down' will clear the 'linklossFwd' reason.
sapEthernetLLFAdminStatus can only be enabled on saps
configured for an EPIPE service using an Ethernet
port with the tmnxPortEncapType set to 'nullEncap.'
