Yes, the API is used by Intel, HP, NextIO and some other anonymous 
companies as they rise questions and send me feedback. I haven't seen 
their works but I guess some of drivers using SR-IOV API are going to be 
released soon.

My test was done with Intel 82576 Gigabit Ethernet Controller. The 
product brief is at 
http://download.intel.com/design/network/ProdBrf/320025.pdf and the spec 
is available at
