Hello,
The reason why IPv6 does not work when using -net socket,mcast=foo is

own frames. When the IPv6 stack performs duplicate addresse detection
(DAD) through a multicasted announce, it receives its own announcement,

is factorized.
Some #define ETH_* are moved upper in slirp.h to make them accessible to
other slirp/*.h

This patch makes solookup() compatible with all address family. Also,
this function was only compatible with TCP. Having the socket list in
argument, it is now compatible with UDP too. Finally, some optimization

This patch simply adds a sa_family_t argument to remove the hardcoded

Before this patch, if sosendto fails, udp_input is executed as if the
packet was sent. This could cause memory leak.

This patch adds IPv6 case in TCP functions refactored by the last
patches.
This also adds IPv6 pseudo-header in tcpiphdr structure.
Finally, tcp_input() is called by ip6_input().

This patch factorizes some duplicate code into a new function,

to the host, the loopback address is used, and if the paquet is

This patch adds an IPv6 address to the DNS relay. in6_equal_dns() is
developed using this Slirp attribute.
sotranslate_in/out() are also updated to manage the IPv6 case so the
guest can be able to join the host using one of the Slirp addresses.

Basically, this patch adds some switch in various TCP functions to
prepare them for the IPv6 case.
To have something to "switch" in tcp_input() and tcp_respond(), a new
argument is used to give them the sa_family of the addresses they are
working on.
