Hi Rick,
I'm afraid that I don't know the answer to your question, however I wanted to ask you a question as we are also imaging machines using SCCM 2012 that have these nic's.
We are finding high UDP packet loss which is affecting programs such as Lync that use real time video. We've also tested using iperf and can see high packet loss.
Have you seen issues similar to this?
Thanks
Steve
