Right, but the question is:
1) is it physically possible for a 15.4g device to send both 15.4g
frames and 15.4-2011 frames?
Another email suggests that this can never happen because frequencies
are never the same. If so, end of problem.
2) if the answer to question 1 is yes, then 15.4g devices need to know
if they are speaking to 15.4-2011 devices, and
a) adjust their frame header bits appropriately.
b) to 6lowpan fraglettation.
