I am not anywhere close to a machine where i can give you precise
details to this; the one thing that sticks out in my brain cells is the
SPI mismatch. This (in static setups) seemed to be the most common
mistake i saw (other than a mismatched key). Your stats as you have them
now and as is will catch both in one spot - which is a good start.

I thought those were part of some MIB somewhere. Doesnt RFC 4898 cover
them?
In any case, it seems to me to be more accurate to not call them MIB
stats if they are not. This doesnt qualify using the macros, utilities
etc used for MIBs.

I am very tempted to say #4. And when you push this to be a real MIB
stat then

Absolutely - it would be much appreciated. And if you dont have time, I
will write and test the user space part extension.
