I can understand that mandatory window size of 1 is not a good idea: it force
to drop every single out-of-order packet. But I don't see any good reason to
force the window size to be 32*X (X >= 1). Shouldn't people be allowed to pick
up any smaller number, let us say 8 or 16, as best fit their application?
Window size of 32*X when X>=2 is quite big to me considering that it is a per
destination/per security association figure.
