ipv4: fix error handling in icmp_protocol.
Now we handle icmp errors in each transport protocol's err_handler, for icmp protocols, that is ping_err. Since this handler only care of those icmp errors triggered by echo request, errors triggered by echo reply(which sent by kernel) are sliently ignored. So wrap ping_err() with icmp_err() to deal with those icmp errors. Signed-off-by: Li Wei <lw@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
