Description (partial)


Topology :
   7600(SRE Throttle which does not have this fix) ------- 7600 (SRC / SRD) 

   Ping failure will happen if cell payload scrambling is turned off on the SRC /SRD image side .

   Turn off cell payload scrambling through CLI on SRE Throttle image side (which does not have 
   this fix) will not have any impact i.e. cell payload scrambling will be always turned on  
   on this image. No matter if it is disabled or enabled through the CLI.

   In SRC / SRD image cell payload scrambling can be turned off or turned on through CLI . 
   Hence if on the src/ srd image side cell payload scrambling is explicitly turned off then 
   there will be a mismatch in scrambling configuration on both sides leading to a data path 
   failure  i.e. ping failure .
