	* (zebra/rtadvc.): can not set checksum for ICMPV6, see:

From: Jun-ichiro itojun Hagino <itojun@iijlab.net>
Subject: [zebra 11052] setsockopt(IPV6_CHECKSUM) does not work for ICMPv6
socket

setsockopt(IPV6_CHECKSUM) does not work for ICMPv6 socket.
RFC2292 may not be clear enough about it (it talks about raw socket
and ICMPv6 socket mixed up), but the next revision
(draft-ietf-ipngwg-rfc2292bis-02.txt) is very clear about it.
>   An attempt to set IPV6_CHECKSUM for an ICMPv6 socket will fail.
