The only difference is the space char after IFF_BROADCAST. This causes the redefinition of IFF_VOLATILE. Warning when compiling iproute2 4.10.0: In file included from ../include/linux/if_tunnel.h:5:0, from iptunnel.c:24: ../include/linux/if.h:130:0: warning: "IFF_VOLATILE" redefined #define IFF_VOLATILE (IFF_LOOPBACK|IFF_POINTOPOINT|IFF_BROADCAST|IFF_ECHO|\ In file included from iptunnel.c:21:0: /home/wong/github/lede-1/staging_dir/toolchain-arm_cortex-a9+vfpv3_gcc-6.3.0_musl_eabi/include/net/if.h:48:0: note: this is the location of the previous definition #define IFF_VOLATILE (IFF_LOOPBACK|IFF_POINTOPOINT|IFF_BROADCAST| \ Best Regards, Syrone Wong
