Thanks, and also thanks to Gilad from Mellanox who put me in contact 
with another person who was able to answer this and other questions.

One valuable thing I learnt was that IPoIB includes neighbor MTU 
information and so a system sending IP packets from a connected mode 
host to a datagram mode host will already know the destinations MTU.
