This is actually perfect. You said that the setup was to connect the Realtek card to the mirror port of a switch. You don't want to be communicating via a port that's a mirror port, you only want to monitor. No risk of confusing the switch, nor the OS on the Engineering Station by mix of traffic. Also no contention on the mirror port.
What you do is stick another NIC in the Engineering Station and use that for the actual network traffic and keep this for monitoring only.
