"ip route show" does not print correct value when larger rto_min is
set (e.g. 3sec).
This problem is because of overflow in print_route() and
the patch below is a workaround fix for that.
[root test]# ./iproute2.git.org/ip/ip route show dev eth1
192.168.140.0/24 proto kernel scope link src 192.168.140.130
169.254.0.0/16 scope link
[root test]# ./iproute2.git.org/ip/ip route change 192.168.140.0/24
dev eth1 rto_min 3s
[root test]# ./iproute2.git.org/ip/ip route show dev eth1
192.168.140.0/24 scope link rto_min lock 2ms <-- wrong
169.254.0.0/16 scope link
[root test]# ./iproute2.git/ip/ip route show dev eth1 # patched version
192.168.140.0/24 scope link rto_min lock 3000ms <-- correct
169.254.0.0/16 scope link
