[j-nsp] Poll Question (VRF scale on MX)

[adamv0025 at netconsultings.com]

It has the same (well 31.8M DWORDs/254.3MB vs 32M DWORDs/256MB) EDMEM RLDRAM as gen1 and 2 trio chips 

But it's not storing ENCAPS in there which gives it additional 4.1M DWORDs in the shared memory which next hops can take from.
