NAME

       ibdm - Solaris InfiniBand Device Manager

DESCRIPTION

       The  Infiniband	Device	Manager  (IBDM) is an IBTF-compliant kernel misc module. IBDM adheres to the InfiniBand Device Management class as
       described in InfiniBand Architecture Specification, Volume 1: Release 1.1 and enumerates all the devices which are  visible  from  a  given
       host  and  maintains  a	data  base of all IB devices visible to the host. IBDM provides interfaces to the IB nexus driver that enables the
       driver to retrieve information about IB devices on the fabric.
