Please have a look at RFC7388 when doing this: Definition of Managed Objects for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs). J. Schoenwaelder, A. Sehgal, T. Tsou, C. Zhou. October 2014. (Format: TXT=53451 bytes) (Status: PROPOSED STANDARD) (DOI: 10.17487/RFC7388)
The writing on the package says its SNMP, but the important thing is the definition of the counters, which have wider applicability.

My rationale for the "old style" of counting was that L2 is the lowest layer where we can analyze traffic from the node's perspective. Hence, I'd like to count every byte/packet the node receives. However, I realized that this might be a bad idea, given different transceiver capabilities. Old or very cheap transceivers leave most packet parsing and error handling to the driver developer. Hence, here the driver will receive a lot more packets than for more advanced transceivers. Hence, we should probably agree that only successful received packets, i.e., packets with header information and correct checksums (if any) targeted to the receiving node (matching destination address) are counted as successful received packets. All other packets may go into an additional "RX error" field of the statistics. However, I would vote that packets that are dropped by the driver, e.g., because of insufficient memory, should _not_ count as "RX error" for L2. We could consider adding another field, e.g. "RX dropped" for this purpose. What do you think?
