/*
* The InfiniBand Nexus driver (IB nexus) is a bus nexus driver for IB bus.
* It supports Port nodes, Virtual Physical Point of Attachment nodes (VPPA)
* for HCAs registered with IBTL and IOC nodes for all the IOCs present in
* the IB fabric (that are accessible to the host). It also supports Pseudo
* device children to be enumerated using their .conf file(s). All Port nodes
* and VPPA nodes are children of HCA drivers. All the IOC nodes and the Pseudo
* device nodes are children of the IB nexus driver.
*
* IB nexus driver provides bus nexus entry points to all the HCA drivers.
*
* IB nexus driver registers with InfiniBand Device Manager (IBDM) to get
* information about all the HCA ports and I/O Controllers (IOCs) connected
* to the IB fabric. Based on that information, IB nexus will create all the
* device tree nodes.
