"struct nx_aggregate_stats_reply" no longer has a member of the
appropriate type. That's the main purpose of the patch: to separate
stats headers from their bodies.

Yeah, I should have done that to begin with.
I added:
enum {
HEADER_LEN = MAX(sizeof(struct ofp_stats_msg),
sizeof(struct nicira_stats_msg));
}
