From 9e357fb4fc00ab9c303e314b85b9ae3836141f81 Mon Sep 17 00:00:00 2001
From: Petr Vorel <petr.vorel@gmail.com>

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.
