As noted on current-users, this inline code breaks ipf on 64-bit architectures,
due to src/sys/dist/ipf/netinet/ip_fil.h:
#define      offsetof(t,m)   (int)((&((t *)0L)->m))

As also pointed out on current-users, either #include'ing <stddef.h>,
fixing the #define, or making the sockaddr_iso_init1 sub (as defined
in sys/netiso/iso.h) non-inlined would all probably suffice to make
things work again.
