Thanks for your reply Simon. As you mentioned in IPv6 world, address resolution packets would be naturally sent to raw IP layer. So when I implement ping_recv function, I need to skip the first received NA frame right. Do you have any recommendation about this? Do I need to keep receive and check ICMPv6 type of every incoming packet until I get an Echo Reply packet?
Sorry, I haven't implemented ping on IPv6 myself, I would have to dig that up myself. But yes, you won't get around parsing the ICMPv6 protocol yourself when doint raw IPv6. Regards, Simon
