States 32k or 64k IFLs for MPC.

I don't think that is hard limit imposed by Trio.

Unit numbers itself only go to 16k, which is real PITA for deriving QinQ
unit-number, where <topvlan><zeropadded bottom vlan> would be obvious
numbering scheme. (Now you need some external mapping table, to map given
QinQ combination to given unit-number)

If you'd do residential DSL termination, each customer in their own (QinQ)
IFL (with shared loopback IPv4 and unique per IFL IPv6) that number looks
quite modest.
But for other application seems sufficient.
