Enable the SNMP code to digest OCTET STRING values acting as proto-Counter64 objects as seen in the FCMGMT-MIB with the following comment:

There is one and only one statistics table for each individual port. For all objects in statistics table, if the object is not supported by the conn unit then the high order bit is set to 1 with all other bits set to zero. The high order bit is reserved to indicate if the object if supported or not. All objects start at a value of zero at hardware initialization and continue incrementing till end of 63 bits and then wrap to zero.
