  Log:
  SVN rev 209611 on 2010-06-30 17:26:47Z by jfv
  
  SR-IOV support added to igb
  
  What this provides is support for the 'virtual function'
  interface that a FreeBSD VM may be assigned from a host
  like KVM on Linux, or newer versions of Xen with such
  support.
  
  When the guest is set up with the capability, a special
  limited function 82576 PCI device is present in its virtual
  PCI space, so with this driver installed in the guest that
  device will be detected and function nearly like the bare
  metal, as it were.
  
  The interface is only allowed a single queue in this configuration
  however initial performance tests have looked very good.
  
  Enjoy!!
