Please can you send a patch against xen-unstable.hg to document this new protocol variant in xen/include/public/io/netif.h. This header is a bit under-documented but lets not let it fall further behind (if you want to go further and document the existing features, in the style of the current blkif.h, then that would be awesome!). You may also want to provide a similar patch to Linux's copy which is in linux/include/xen/interface/io/netif.h Ian.
