GMPLS update - 20: optimizing standard in-segment statistics entries

#Updated #standard #in-segment #statistics agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to #use standard #in-segment entry based #indexing. This will access the port entries by using the #native #indexing. This removes references to the standard in-segment statistics indexing used earlier. The in-segment statistics #entries add support for #in-segment #counter #attributes like #packets and #bytes #forwarded, #packet #errors and #discards during #forwarding, etc ...
