Right, after reviewing this code again I see that it is possible
failure.

We don't have appropriate indication in the vendor layer. I think non-IB
devices can be filtered out in osm_vendor_get_all_port_attr(), something
like this:
diff --git a/opensm/libvendor/osm_vendor_ibumad.c
b/opensm/libvendor/osm_vendor_ibumad.c
index 522325b..977a3b2 100644

if (umad_get_ca(p_vend->ca_names[i], &ca) == 0) {
+ if (ca.node_type < 1 || ca.node_type > 3)
+ continue;
for (j = 0; j <= ca.numports; j++) {
if (!ca.ports[j])
continue;
