Log Message:
Pull up following revision(s) (requested by bouyer in ticket #295):
sys/external/bsd/ipf/netinet/ip_fil_netbsd.c: revision 1.40
Explicitely check a pointer against NULL before computing a member address,
to avoid undefined behavior. Avoids the same NULL pointer check being
"optimised" later, leading to NULL pointer dereference.
It is expected that -fno-delete-null-pointer-checks would avoid this but
it does not.
