netfilter: ip6_tables: add flags parameter to ipv6_find_hdr()
This patch adds the flags parameter to ipv6_find_hdr. This flags
allows us to:
* know if this is a fragment.
* stop at the AH header, so the information contained in that header
can be used for some specific packet handling.
This patch also adds the offset parameter for inspection of one
inner IPv6 header that is contained in error messages.
