With the -M option you actual disable the PMTUD mechanism, not IP fragmentation at all. This means that no dynamic mechanism is involved, on the contrary, the MTU size of the outgoing interface is used. Standard is to enable path MTU discovery. ~3 month ago there where a interesting discussion on the netdev mailinglist, maybe you should grep the netdev archive for some background information.
