Look at my previous mail, by the way. It covers this.

Well, just a note: driver has to transform in any case,
f.e. to canonicalize the number to host word order.

I proposed to solve all the issues in one shot: no transforms,
direct access, set of offsets.

Well, and provided bits remain undefined, everyone will use
only u32 part.

What's about MIBs, it is _user_ _space_ thing, they can be 256 bit
with the same success and equally easily.

OK, I will wait with rates until such hardware will appear. :-)
