Wow! That's impressive.  I am looking forward to the next wave of distro
releases.

This is interesting.  Looks like the MC7710 firmware only counts TX, but
that's also where we have the biggest difference between the driver view
and the network view. The numbers shows that the firmware counts
considerably less bytes than the driver:

I assume the firmware is somewhat closer to reality, but I still think
the number looks high. Guess we won't know for sure until I start
working on additional driver counters.  Have no idea when that will
happen.  Probably not on this side of the summer..
