I see in ompi/mca/btl/openib/btl_openib/connect/btl_openib_connect_oob.c and .../btl_openib_connect_xoob.c what looks like assignments of the form

   path_mtu = MIN( device_mtu, remote_mtu );

In ompi/mca/btl/openib/btl_openib/connect/btl_openib_connect_oob.c(289) it looks correct:

        enum ibv_mtu mtu = (openib_btl->device->mtu < endpoint->rem_info.rem_mtu) ?
            openib_btl->device->mtu : endpoint->rem_info.rem_mtu;

However, in ompi/mca/btl/openib/btl_openib/connect/btl_openib_connect_xoob.c(462 and 563), it looks suspicious (different remote_mtu's):

    attr.path_mtu = (openib_btl->device->mtu < endpoint->rem_info.rem_mtu) ?
        openib_btl->device->mtu : rem_info->rem_mtu;

Can someone verify that the code in ompi/mca/btl/openib/btl_openib/connect/btl_openib_connect_xoob.c is correct?
