This is necessary to support heterogeneous pools. For example, if you have
an ipv6 addressed network, you'll want to be able to forward ipv4 traffic
into it.
This patch enforces that destination address family is the same as service
family, as none of the forwarding mechanisms support anything else.
For the old setsockopt mechanism, we simply set the dest address family to
AF_INET as we do with the service.

It was wrong (bigger) but problem is harmless.

By default the SH scheduler rejects connections that are hashed onto a
realserver of weight 0. This patch adds a flag to make SH choose a
different realserver in this case, instead of rejecting the connection.
The patch also adds a flag to make SH include the source port (TCP, UDP,
SCTP) in the hash as well as the source address. This basically allows
for deterministic round-robin load balancing (i.e., where any director
in a cluster of directors with identical config will send the same
packet the same way).
The flags are service flags (IP_VS_SVC_F_SCHED*) so that these options
can be set per service. They are set using a new option to ipvsadm.

Some service fields are in network order:
- netmask: used once in network order and also as prefix len for IPv6
- port
Other parameters are in host order:
- struct ip_vs_flags: flags and mask moved between user and kernel only
- sync state: moved between user and kernel only
- syncid: sent over network as single octet
