>Description:
When using traceroute, and multiple paths exist, we currently get a
ugly and hard to read output like the below
$ /usr/sbin/traceroute pannxt1
traceroute to pannxt1.ip.tele.dk (195.249.8.42), 30 hops max, 40 byte packets
1 eth9-0-0.sltnxt2.ip.tele.dk (193.162.159.76) 1.098 ms 0.885 ms 0.833 ms
2 pos0-3.155M.arcnxg2.ip.tele.dk (195.249.12.245) 0.988 ms 1.003 ms 0.901 ms
3 atm0-0-0-72.60M.abnxt2.ip.tele.dk (195.249.11.25) 16.220 ms 8.541 ms 8.289 ms
4 fe1-0-0.100M.abnxt1.ip.tele.dk (195.249.112.225) 11.734 ms 8.727 ms 10.048 ms
5 ser3-0.bstnxt1.ip.tele.dk (195.249.13.45) 11.791 ms ser6-2.bstnxt1.ip.tele.dk (195.249.13.69) 9.034 ms ser3-1.bstnxt1.ip.tele.dk (195.249.4.109) 8.462 ms
6 ser3-2.pannxt1.ip.tele.dk (195.249.5.21) 8.954 ms * 9.245 ms
With my patch the output is much nicer

>How-To-Repeat:
run traceroute to a distination where multiple paths exist.
>Fix:
Apply the below patch to /usr/src/contrib/traceroute/traceroute.c
