Looks like this is not defined anywhere: HAVE_IBV_LINK_LAYER_ETHERNET, which
causes
btl_openib_connect_oob.c:oob_component_query() to falsely claim oob support for
iwarp devices.
In 1.7.1 we see this in oob_component_query():
#if defined(HAVE_STRUCT_IBV_DEVICE_TRANSPORT_TYPE)
if (BTL_OPENIB_CONNECT_BASE_CHECK_IF_NOT_IB(btl)) {
opal_output_verbose(5, mca_btl_base_output,
"openib BTL: oob CPC only supported on InfiniBand;
skipped on %s:%d",
ibv_get_device_name(btl->device->ib_dev),
btl->port_num);
return OMPI_ERR_NOT_SUPPORTED;
}
#endif
In 1.7.2, it adds the HAVE_IBV_LINK_LAYER_ETHERNET define:
#if defined(HAVE_STRUCT_IBV_DEVICE_TRANSPORT_TYPE) &&
defined(HAVE_IBV_LINK_LAYER_ETHERNET)
if (BTL_OPENIB_CONNECT_BASE_CHECK_IF_NOT_IB(btl)) {
opal_output_verbose(5, mca_btl_base_output,
"openib BTL: oob CPC only supported on InfiniBand;
skipped on %s:%d",
ibv_get_device_name(btl->device->ib_dev),
btl->port_num);
return OMPI_ERR_NOT_SUPPORTED;
}
#endif
