Re: Call for Consensus: Frame size (to address #553)

+1 to expanding to 24 bits with a setting (while 16k may be good based on
current data, experience has shown that these sorts of things change
dramatically over a decade or two).

Where does the 256 octet minimum come from?  That seems like an arbitrary
value.  Is it too low?   The minimum values have ended up mattering in
other protocols  (the IPv4 minimum bleeding over into impacting DNS, etc)
so we should be careful not to set it too low.
