I suspect that, rather than disabling CM at compile-time, you
are disabling CM at run-time. Please note that this only affects
outgoing but not incoming packets (this is implied by spec, since
CM support is signalled by a bit in hardware address).

To really test interoperability with datagram mode, install OFED without CM
support on one side.
