fabric with a 2K MTU, the IPoIB MTU will be 2048 - 4 = 2044 bytes.

In connected mode, the IB RC (Reliable Connected) transport is used.
Connected mode is to takes advantage of the connected nature of the
IB transport and allows an MTU up to the maximal IP packet size of
64K, which reduces the number of IP packets needed for handling
large UDP datagrams, TCP segments, etc and increases the performance
for large messages.

In connected mode, the interface's UD QP is still used for multicast
and communication with peers that don't support connected mode. In
