I couldn't find such a function in the kernel.

These are hardware stats ... presumably useless without
a detailed understanding of the guts of the e1000.

I can't imagine what generic interface would allow these

Now *these* are generic ... and fixing this so that the
stats increment instead of over-riding would take
maybe half-an-hour or so; this is not hard to do ... !?
Do you want me to write a patch to do this?
