FIX: Slow performance for Hyper-V VMs when using VMQ with Broadcom NICs

Regarding to the issue I mentioned in my post about the performance issues from Hyper-V VMs when VMQ is enabled, Broadcom brought a driver fix for Windows Server 2012.

This fix should solve the issue.

You can download the new firmware from Broadcom or your the downloadpages from your Vendor.
