  1. move the isDevice(l.host, pi) to be first, as no need to iterate on all nics if it returns true
  2. first compare by name, as same nics will have same names
  3. if not found by name, compare by ips.

the bug was the strings.HasPrefix
2 different nics with ipv6:

#nic1 ip: f1234::55
#nic2 ip: f1234::55::66::66

so because of the strings.HasPrefix it was evaluated as the name nics. but they are not.

@buger ^
it should also be a fix to release-1.3
