[a-nsp] 7170 platform ... ?

[Bryan Holloway]

Curious if any folks out there have had any experiences (good or bad) 
with the Tofino/P4 chipset on Aristas.

We're intrigued by the possibilities, but Arista's datasheets have a lot 
of "asterisk'd" L2/L3 features -- i.e., "not supported in EOS" -- and 
I'm wondering what kind of timelines one should expect for getting these 
things implemented.

E.g.: PIM-SM, uRPF, PBR ...
