It absolutely requires its own ethernet port, no router either. That's because it's a realtime device and having to arbitrate would only make unpredictable latency/jitter.
Like others are saying, the link for accessing your LAN probably won't even suffer if you use wifi and a USB2.0. I just used a Edimax Wireless N150 Wifi Nano. $10. People use 'em all the time for Raspberry Pi. Immediately worked on Linux. No speed complaints.
