I believe it is intentional.  IIRC, ip_fw.h varies incompatibly
between kernel versions, so there is no "correct" version we could put
in glibc.

So the only solution is to make your own ip_fw.h which contains the
structure definitions you wanted.

I suppose we could come up with some kind of header file by including
all the different structure definitions from the kernel, so you'd have

struct ip_fwpkt_k2_0
struct ip_fwpkt_k2_2

and whatever other versions are necessary.
