Lenovo USB3 Dock Ethernet Not Working After Upgrading to 7.6

I was previously running 7.4M0 on a Lenovo X1 Carbon Touch with a Lenovo USB 3 Dock. Ran fine on Windows 8. After I upgraded to Win 8.1, I went to refresh all drivers, including attempting to upgrade to the latest DisplayLink version 7.7. However, I found that this caused the dock ethernet to not work... The link never came up in software and I can see the activity light on the network switch port that the dock is connected to turn on for about one second, then off for two, then back on. It just cycles like that indefinitely. I found that 7.6M2 performed the same, but that 7.5M2 seems to work fine.

Any thoughts on what might be happening and what might have changed between 7.5 and 7.6 to cause this?

Thanks.
