This object represents the higher word value of the counter
associated with the number of packets received without a CDL
header on this interface.
NOTE: The object coCdlRxNonCdlPackets 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
coCdlHCRxNonCdlPackets object directly which is a 64 bit
counter.
