Huh ??? I would have thought that fragmentation could only occur
if a packet that was _bigger_ than the MSS was to be sent, so
you _should_ advertise a big limit. Of course, the effective value
that will be used is still negotiated with the other end (your ISP)
but it makes sense to allow for bigger values, if the other end
also supports them ...
On the other hand, with bigger packets what you can have is not
fragmentation but transmission errors (especially with modem links)
where the retry will have to transmit the whole packet again ...
