FWIW, on the openib-cpc2 branch, the base data that is sent in the
modex is this:

     uint64_t subnet_id;
     /** LID of this port */
     uint16_t lid;
     /** APM LID for this port */
     uint16_t apm_lid;
     /** The MTU used by this port */
     uint8_t mtu;

lid is used by both the xoob and ibcm cpc's. We can skip packing the
apm_lid if apm support is not used if you really want to. The MTU has
been changed to the 8 bit enum value.
