We only have one (input) interface error counter, and that counts dropped
packets for many reasons.
So either you need another per-interface counter to distinguish
the reason why things got dropped, probably too much of a change,
or keep the single counter for all reasons.
I would add a global counter and/or a histogram to report "unknown protocols"
(or all protocols).
