This object represents the higher word value of the counter
associated with the number of CDL Header CRC errors
encountered in the receive direction.
NOTE: The object coCdlRxHecError contains the lower 32 bits of
this counter value. If the error count is greater than
4,294,967,295, the higher word value will be stored in this
object. SNMP v2c or v3 managers can use the
coCdlHCRxHeaderCRCError object directly which is a 64 bit
counter.
