Hi Chip et al,

Here, I hope, is my final comment on frame sizes. Characterizing
minimum-length SONET frames as being of "no practical use" is
problematic, in that practicality is relative to the user.

I know you really mean "no practical use in any conceivable production
setting" but that's beside the point in the context of bmwg docs.
Certainly for any tester asked to determine maximum switch fabric
performance, the use of minimum-length frames is not only practical but
necessary.

I'd suggest deleting this paragraph:

"Note: The 47 bytes SONET frame has no practical use since it can carry
only the 40 bytes
header of an IPv6 packet and no upper layer protocol information.  It
represents however
the smallest frame size for this media type.?

If I were going to offer any comment on minimum-length SONET frames, it
would be to note that the minimum length may be 47 or 49 bytes depending
on the CRC field length in use.
