Here are my two questions for clarification:

1. A common problem in networks is Link Aggregate Group (LAG) component
links that have MTU mis-matches.  Is there a way to use this mechanism to
help detect this condition?

2. There is a draft in BFD, draft-ietf-bfd-large-packets, that provides a
mechanism to test MTU.  Are you aware of this draft?  If so, have you
considered how you might expose detected path MTU in your feature?
