tnRoeTargetOffsetNano

The time is in the unit of nanosecond for provisioned
target delay.  The parameter is available only when CPRI
port is set to structure-aware mode.
Represent the provisioned target delay
 - In DL path : BBU CPRI egress to remote TPS CPRI egress
 - In UL path : remote TPS CPRI ingress to BBU CPRI ingress
 - For remote TPS provision : target-offset should be based
   on DL path.
 - For hub TPS provision : target-offset should be based on
   UL path.
This parameter is used to calculate the TPS CPRI egress
presentation time setting (ie CPRI 10ms frame boundary is
egress at specific presentation time based on TPS timebase
traceable to global time reference).   All demapper buffers
are egress based on this alignment.  The offset time should
be designed considering all factors introducing latency,
i.e., network transmission latency, Ethernet switch
forwarding latency, RoE encap/decap latency, jitter buffer
depth, timebase difference between mapper and demapper.
This parameter can be modified at run time, but the
corresponding RoE demapper should be shut-down and no
shutdown so that the decapsulated CPRI signals are played
out at the presentation time.
