title: c++ code for send ICMPv6 with neighbor solicitation
body: <p>I spend a lot of time with compose ICMPv6 with neighbor solicitation by pcap. I studied RFC:</p>
  
  <p>rfc4861#section-4.3</p>
  
  <p>rfc4443#section-2.3</p>
  
  <p>But I did not be able made correct checksum. As a next step a try tu find some example in C/C++. I found ns.c from <a href="http://www.pdbuchan.com/rawsock/rawsock.html" rel="nofollow noreferrer">http://www.pdbuchan.com/rawsock/rawsock.html</a> and it is not probably good implementaion. Function <em>sendmsg()</em> doing segmentation fault and checksum is not correct too ... I think.</p>
  
  <p>If someone know about code, which sending neighbor solicitation,I will be grateful.</p>
  
  <p>If someone one know why code doesn't I will be grateful too.</p>
  
  <p>thanks</p>
