Subject: iproute2: prints bogus hoplimit


$ ip -6 r
fc00::/7 dev rtl0  proto kernel  metric 256  mtu 1500 advmss 1440 
hoplimit 4294967295

Most likely, "hoplimit -1" would be the right number, though I am not 
sure if simply changing %u by %d is a correct thing to do, since it 
would affect all fields.
