.B IPV6_UNICAST_HOPS
Set the unicast hop limit for the socket. Argument is an pointer to an
integer. \-1 in the value means use the route default, otherwise it should be
between 0 and 255.
.B IPV6_ADDRFORM
Turn an
.I AF_INET6
socket into a socket of a different address family. Only
.I AF_INET
is currently supported for that. It is only allowed for IPv6 sockets
that are connected and bound to a v4-mapped-on-v6 address. The argument
is a pointer to a integer containing
.BR AF_INET .
This is useful to pass v4-mapped sockets as file descriptors to
programs that don't know how to deal with the IPv6 API.

.B IPV6_ADD_MEMBERSHIP, IPV6_DROP_MEMBERSHIP
Control membership in multicast groups. Argument is a pointer to a
