Also other than the typo in the title there ;) I'm going to CC the driver maintainers working on XDP (makes for a long CC list but) because we would want to try and get support in as many as possible in the next merge window. For this rev I just implemented on ixgbe because I wrote the original XDP support there. I'll volunteer to do virtio as well. Thanks, John
