I am seeing this same issue with the I217-LM. My case is slightly simpler. I too am using Windows 8.1 x64 fully patched up. I have a Dell M4800 with an i7-4910MQ CPU. It has no other NIC devices (wieless adapter devices disabled in the BIOS). I have the most recent Dell BIOS and Intel Drivers (12.13.17.4). I have no VLANs (and of course, no teaming since there's nothing to team to...). The link is auto/auto just like the switch port and is negotiating 1000/Full.
I actually stumbled upon this thread and I'm glad I did. I had simply assumed that the RSS was working, and not thought to check it this way. I was actually trying to find out if I could increase the number of RSS Queues to 4 since I have 4 physical cores (I knew you have to discount the Hyper-Threaded cores).
