I am currently running xen-4.3.3 on gentoo (dom0 is based on kernel 3.17.7) and I am happy to help out by applying and testing patches on my version.

Looks like xen-netback was never converted to the 64 bit stats interface like e.g. netfront was (see commit e00f85bec0a9 in ~v3.1). I could have sworn netback changed eons ago -- I was clearly mistaken. Ian.
