I have used Intel 82576EB > emulator in QEMU [1] to test the changes to IGB driver. I gave this patch series a try on a recent kernel and silicon (i210). There was one issue in igb_xmit_zc(). But other than that it worked very nicely. It seems like it hasn't been merged yet. Do you have any plans for continuing to work on this?
