Folks,

I just performed the first successful ping between RARE running on the
AS9516_32D and a Cisco 8201 via a 400G port :)

The last hurdle was to find out which port on the Tofino2 chip
represents the CPU PCIe port that provides the communication to the
control plane. Lacking documentation I had to do this by trial and
error. Luckily, the first try was a success: it's device port #0 (but
maybe Tofino2 has more than one, I don't know).

Most of the code is already in the various Git repos, but not all of
it. I'll try to do this later today or next week.
