NetMaster Level 2 Support clarified it in detail for us:
While NetMaster does indeed use the EZBNMIFR API to gather TCP/IP informatiion, it only uses a couple of specific calls, such
as TCP Connections, Global Stats, and Interface Information. In review of the PH19158 HIPER, it specifically mentions the
GetTnProfile request. NetMaster does not currently use or support that request type. So NetMaster isn't exposed
to this particular problem.
