jfv 2010-06-30 17:26:47 UTC FreeBSD src repository Modified files: sys/dev/e1000 if_igb.c if_igb.h 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!!
