Well, this is leftover from keeping track of different versions of the
out-of-tree patch, and we already broke compatibility pretty thoroughly
as a preparation for upstreaming. So I'm fine with dropping the version
check; will resend.
That being said, the versioning comes from the XSTATS API, which does
not use netlink attributes for its members, but rather passes through as
struct. So what is one supposed to do in this case?
