If icmp_send is changed to use inet_addr_type() then ICMP will leave
with saddr != VIP and that is not nice.

I'm not familiar with the IPVS terms, but as far as I understand,
it is _not_ going to return RTN_LOCAL, so we get the desired
behaviour of selecting a local address as source.

    But what is preferred is to use VIP in ICMP.

ip route add local VIP dev lo table user_defined

    returns RTCF_LOCAL but inet_addr_type() does not return RTN_LOCAL,
we fix one thing but break another :)

Well, I have promissed you to give some feedback after I test the patch
proposed by Patrick, but after Julian's post I can only confirm that it
works exactly as Julian said, what is not what I would expect.

It will pick a local source address and use that. I don't see why
it matters whether its the VIP address or some other.
