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.
