NAME

       ibnd_discover_fabric, ibnd_destroy_fabric, ibnd_debug ibnd_show_progress - initialize ibnetdiscover library.

SYNOPSIS

       #include <infiniband/ibnetdisc.h>

       void ibnd_destroy_fabric(ibnd_fabric_t *fabric)
       void ibnd_debug(int i)
       void ibnd_show_progress(int i)
       int ibnd_set_max_smps_on_wire(int i)

DESCRIPTION

       ibnd_discover_fabric() Discover the fabric connected to the port specified by ibmad_port, using a timeout specified.  The "from" and "hops"
       parameters are optional and allow one to scan part of a fabric by specifying a node "from" and a number of hops	away  from  that  node	to
       scan, "hops".  This gives the user a "sub-fabric" which is "centered" anywhere they chose.

       ibmad_port must be opened with at least IB_SMI_CLASS and IB_SMI_DIRECT_CLASS classes for ibnd_discover_fabric to work.

       ibnd_destroy_fabric() free all memory and resources associated with the fabric.

       ibnd_debug() Set the debug level to be printed as library operations take place.

       ibnd_show_progress() Indicate that the library should print debug output which shows it's progress through the fabric.

       ibnd_set_max_smps_on_wire() Set the number of SMP's which will be issued on the wire simultaneously.

RETURN VALUE

       ibnd_discover_fabric() return NULL on failure, otherwise a valid ibnd_fabric_t object.

       ibnd_destory_fabric(), ibnd_debug() NONE

       ibnd_set_max_smps_on_wire() The previous value is returned

EXAMPLES

       Discover the entire fabric connected to device mthca0 , port 1.

	    int  mgmt_classes[2]  =  {IB_SMI_CLASS,  IB_SMI_DIRECT_CLASS};	 struct  ibmad_port  *ibmad_port  = mad_rpc_open_port(ca, ca_port,
       mgmt_classes, 2);      ibnd_fabric_t *fabric = ibnd_discover_fabric(ibmad_port, 100, NULL, 0);	   ...	      ibnd_destroy_fabric(fabric);
	    mad_rpc_close_port(ibmad_port);

       Discover only a single node and those nodes connected to it.

	    ...       str2drpath(&(port_id.drpath), from, 0, 0);      ...	ibnd_discover_fabric(ibmad_port, 100, &port_id, 1);	 ...
