slirp: Adding IPv6, ICMPv6 Echo and NDP autoconfiguration
This patch adds the functions needed to handle IPv6 packets. ICMPv6 and NDP headers are implemented. Slirp is now able to send NDP Router or Neighbor Advertisement when it receives Router or Neighbor Solicitation. Using a 64bit-sized IPv6 prefix, the guest is now able to perform stateless autoconfiguration (SLAAC) and to compute its IPv6 address. This patch adds an ndp_table, mainly inspired by arp_table, to keep an NDP cache and manage network address resolution. Slirp regularly sends NDP Neighbor Advertisement, as recommended by the RFC, to make the guest refresh its route. This also adds ip6_cksum() to compute ICMPv6 checksums using IPv6 pseudo-header. Some #define ETH_* are moved upper in slirp.h to make them accessible to other slirp/*.h Signed-off-by: Guillaume Subiron <maethor@subiron.org> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Reviewed-by: Thomas Huth <thuth@redhat.com>
