No. Haven't planed that yet. > Is there something common with igb_uio? AFAIK igb_uio is mapping the bars via UIO. The Xen netfront driver isn't simulating a PCI interface. Instead it directly maps the TX/RX ring. Overlap is limited to reading sysfs files. Don't know if that is worth being extracted into a standalone header.
