That sounds reasonable to me, at least for nmbjumbop, but I'm not sure
that the larger 9k and 16k clusters are used outside of drivers, so
the nmbclusters limit may be too large for them. But I suppose some
limit is better than none :)

SCTP uses the best fit size for user data.. thus 16k gets used
for large messages :-)
