Demonstration for how to use new API in smpquery:

We're getting SMI/GSI details and need to pass the relevant ibmad_port/CA name to the required methods depending if it is using SMI/GSI calls.
For example:
resolve_portid_str is using inside a GMP calls
(in case  dest_type is not IB_DEST_DRSLID) so we're passing it the gsi name and gsi port
smp_query_via is using SMP calls so we're passing it the smi port
