+\fB\-\-subnet_prefix\fR <PREFIX in hex>
+This option specifies the subnet prefix to use in
+on the fabric. The default prefix is
+0xfe80000000000000. OpenMPI in particular requires
+separate fabrics plugged into different ports to
+have different prefixes or else it won't run.

\fB\-\-smkey\fR <SM_Key value>
This option specifies the SM\'s SM_Key (64 bits).
This will effect SM authentication.
