I guess not but we might have a different understanding of when to
reset. From my point of view the only reason to reset any meta data
is to provide a certain scope a set of new fresh and clean sheets
to play around. Assuming we define global as everything and local
as per device/(ingress|egress) then we definitely need to invoke
a reset on the way over to egress.
