The 'ping' utility is able to manage two kind of sockets (raw or icmp), depending on the sysctl ping_group_range. By default, ping_group_range is set to '1 0', which forces ping to use an ip raw socket. Let's replay the ping tests by allowing 'ping' to use the ip icmp socket. After the previous patch, ipv4 tests results are the same with both kinds of socket. For ipv6, there are a lot a new failures (the previous patch fixes only two cases).
