Add a type for Infiniband ports and an access vector for subnet management packets. Implement the ib_port_smp hook to check that the caller has permission to send and receive SMPs on the end port specified by the device name and port. Add interface to query the SID for a IB port, which walks the IB_PORT ocontexts to find an entry for the given name and port.
