Subject: superfluous space char in marco
For include/net/if.h, we define it as
#define IFF_VOLATILE (IFF_LOOPBACK|IFF_POINTOPOINT|IFF_BROADCAST| \
IFF_ECHO|IFF_MASTER|IFF_SLAVE|IFF_RUNNING|IFF_LOWER_UP|IFF_DORMANT)
while iproute2 4.10.0 define it as
#define IFF_VOLATILE (IFF_LOOPBACK|IFF_POINTOPOINT|IFF_BROADCAST|IFF_ECHO|\
IFF_MASTER|IFF_SLAVE|IFF_RUNNING|IFF_LOWER_UP|IFF_DORMANT)
in include/linux/if.h. 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

note: this is the location of the previous definition
#define IFF_VOLATILE (IFF_LOOPBACK|IFF_POINTOPOINT|IFF_BROADCAST| \
