       ib - InfiniBand device driver configuration files

       The  InfiniBand	(IB)  bus  is an I/O transport based on switched  fabrics. IB devices are
       managed by the ib(7D) nexus driver. There are three categories of InfiniBand devices:

	   o	  IB  port/IB VPPA/IB HCA_SVC devices

	   o	  IB IOC devices

	   o	  IB Pseudo devices

       The IB  port/IB VPPA/IB HCA_SVC devices are enumerated by way of  the  ib.conf  file.  See

       The  IB	IOC  devices  are  enumerated  using  the InfiniBand Device management class. See

       For devices not in these two categories, most notably IB Pseudo devices, the  driver  must
       provide configuration files to inform the system of the IB  devices to be created. Config-
       uration parameters are represented in the form of name value pairs you can retrieve  using
       the DDI property interfaces. See ddi_prop_op(9F) for details.

       Configuration  files  for  IB device drivers must identify the parent driver explicitly as
       ib, and must create a string array property called unit-address which is  unique  to  this
       entry  in  the  configuration file. Drivers name ibport and ioc are reserved by ib(7D) and
       should not be used.

       Each entry in the configuration file creates  a	prototype  devinfo  node.  Each  node  is
       assigned  a  unit  address which is determined by the value of the unit-address	property.
       This property is only applicable to children  of  the  IB  parent  and  is  required.  See
       driver.conf(4) for further details on configuration file syntax.

       Example 1: Sample configuration file

       Here  is a configuration file called ibgen.conf for an IB  device driver that implements a
       generic IB driver. This file creates a node called ibgen.
