Hello BJXT, thanks a lot for posting your inquire at Intel communities.
I would like to tell you that this feature is specific for Server boards. http://www.intel.com/support/motherboards/server/sb/CS-033983.htm
In addition to that, it is necessary to have an Intel® Ethernet Adapter for SR-IOV support and the DH87RL does not have one.
You will be able to find additional information on this URL.
