Thanks, that is very useful information.

Does this ensure that the trailing 3 octets of .all and .ip6 are 0?

I haven't run any tests to confirm the problem, but I am a Dev,
so I can get it fixed :-)
I am a little concerned that this fix may not be correct in
some bizzare case where the packing means that .ip, .ip6[0] and
.all[0] are not the same thing.
I have sent an email to lvs-devel and netfilter-devel to try
and get some discussion on this. The subject of that email is
"[bug] FWMARKs and persistence in IPVS: The Use of Unions".
