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!!
