+// EthernetFrameExtendedPm64Bit (class ID #426)
+//	This ME collects some of the PM data at a point where an Ethernet flow can be observed. It is
+//	based on the Etherstats group of [IETF RFC 2819] and [IETF RFC 2863]. Instances of this ME are
+//	created and deleted by the OLT. References to received frames are to be interpreted as the
+//	number of frames entering the monitoring point in the direction specified by the control block.
+//
+//	For a complete discussion of generic PM architecture, refer to clause I.4.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. To facilitate
+//			discovery, the identification of instances sequentially starting with 1 is encouraged. (R,
+//			setbycreate) (mandatory) (2 bytes)
+//
+//		Interval End Time
+//			Interval end time: This attribute identifies the most recently finished 15-min interval. If
+//			continuous accumulation is enabled in the control block, this attribute is not used and has the
+//			fixed value 0. (R) (mandatory) (1 byte)
+//
+//		Control Block
+//			(R, W, setbycreate) (mandatory) (16 bytes)
+//
+//		Drop Events
+//			Drop events:	The total number of events in which frames were dropped due to a lack of resources.
+//			This is not necessarily the number of frames dropped; it is the number of times this event was
+//			detected. (R) (mandatory) (4 bytes)
+//
+//		Octets
+//			Octets:	The total number of octets received, including those in bad frames, excluding framing
+//			bits, but including FCS. (R) (mandatory) (4 bytes)
+//
+//		Frames
+//			Frames:	The total number of frames received, including bad frames, broadcast frames and
+//			multicast frames. (R) (mandatory) (4 bytes)
+//
+//		Broadcast Frames
+//			Broadcast frames: The total number of received good frames directed to the broadcast address.
+//			This does not include multicast frames. (R) (mandatory) (4 bytes)
+//
+//		Multicast Frames
+//			Multicast frames: The total number of received good frames directed to a multicast address. This
+//			does not include broadcast frames. (R) (mandatory) (4 bytes)
+//
+//		Crc Errored Frames
+//			CRC errored frames: The total number of frames received that had a length (excluding framing
+//			bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had either a bad
+//			FCS with an integral number of octets (FCS error) or a bad FCS with a non-integral number of
+//			octets (alignment error). (R) (mandatory) (4 bytes)
+//
+//		Undersize Frames
+//			Undersize frames: The total number of frames received that were less than 64 octets long but
+//			were otherwise well formed (excluding framing bits, but including FCS octets). (R) (mandatory)
+//			(4 bytes)
+//
+//		Oversize Frames
+//			Oversize frames: The total number of frames received that were longer than 1518 octets
+//			(excluding framing bits, but including FCS octets) and were otherwise well formed. (R)
+//			(mandatory) (4 bytes)
+//
+//		Frames 64 Octets
+//			Frames 64 octets: The total number of received frames (including bad frames) that were 64-octets
+//			long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Frames 65 To 127 Octets
+//			Frames 65 to 127 octets: The total number of received frames (including bad frames) that were
+//			65..127 octets long, excluding framing bits but including FCS. (R) (mandatory) (4 bytes)
+//
+//		Frames 128 To 255 Octets
+//			Frames 128 to 255 octets: The total number of frames (including bad frames) received that were
+//			128..255 octets long, excluding framing bits but including FCS. (R) (mandatory) (4 bytes)
+//
+//		Frames 256 To 511 Octets
+//			Frames 256 to 511 octets: The total number of frames (including bad frames) received that were
+//			256..511 octets long, excluding framing bits but including FCS. (R) (mandatory) (4 bytes)
+//
+//		Frames 512 To 1 023 Octets
+//			Frames 512 to 1-023 octets: The total number of frames (including bad frames) received that were
+//			512..1-023 octets long, excluding framing bits but including FCS. (R) (mandatory) (4 bytes)
+//
+//		Frames 1024 To 1518 Octets
+//			Frames 1024 to 1518 octets: The total number of frames (including bad frames) received that were
+//			1024..1518 octets long, excluding framing bits but including FCS. (R) (mandatory) (4 bytes)
