smi.GetParentNode() seems to always return the Node and not the Parent

Hi,
I'm using smi.GetParentNode() and it always seems to return the same node that I pass it as a parameter instead of that node's parent.

e.g. The following code

node, _ := gosmi.GetNodeByOID(oid)
log.Printf("node name: %s::%s of %s", GetModule().Name, node.Name, node.Kind)
parent := gosmi.CreateNode(smi.GetParentNode(node.GetRaw()))
log.Printf("parent name: %s::%s of %s", parent.GetModule().Name, parent.Name, parent.Kind)

produces the output

bug 2021/03/20 13:08:47 node name: IF-MIB::ifPhysAddress of Scalar
bug 2021/03/20 13:08:47 parent name: IF-MIB::ifPhysAddress of Scalar

when I'm expecting it to produce the output

bug 2021/03/20 13:08:47 node name: IF-MIB::ifPhysAddress of Scalar
bug 2021/03/20 13:08:47 parent name: IF-MIB::ifEntry of Column

I couldn't help but notice that the smi.GetParentNode() function searches for the given node a lot, but never actually dereferences the Parent field. That's probably the problem. Those data structures are sufficiently complicated that I can't work out what the correct fix is. (Any data structure in any programming language that handles ASN.1 source seems to be complicated).

Cheers

Your analysis is absolutely correct. New release coming your way momentarily.
