+Subject: [PATCH] lapi/if_addr.h: Define IFA_F_NOPREFIXROUTE
+
+and use it in icmp_rate_limit01.c.
+
+This fixes error on toolchains with very old kernel headers, e.g.
+Buildroot sourcery-arm:
+
+icmp_rate_limit01.c:82:3: error: 'IFA_F_NOPREFIXROUTE' undeclared (first use in this function)
+   IFA_F_NOPREFIXROUTE);
+
+Fixed because IFA_F_NOPREFIXROUTE was added in 3.14 and the oldest
+system we still support is Cent0S 7 with 3.10 kernel.
+
+NOTE: Cent0S 7 is obviously heavily patched thus it contains
+IFA_F_NOPREFIXROUTE and therefore CI build didn't catch this error.
