Seems like gcc (4.8.3) doesn't catch this false positive, triggering
after 0f7543322c5f ("route: ignore RTAX_HOPLIMIT of value -1"):
iproute.c: In function 'print_route':
iproute.c:301:12: warning: 'val' may be used uninitialized in this function
[-Wmaybe-uninitialized]
features &= ~RTAX_FEATURE_ECN;
^
iproute.c:575:10: note: 'val' was declared here
__u32 val;
^
So just shut it up by initializing to 0.
