Right now, I'm a bit sceptic to this patch, as the JJO fixed a bug
related to the --multihome feature by moving over to IPV6_RECVPKTINFO
commit 5d6dbb03776de4d38f45e429ef674313a2bda8cc

* fix --multihome for ipv6: IPV6_RECVPKTINFO
- setsockopt IPV6_RECVPKTINFO (not IPV6_PKTINFO!) <<<< [1]
- do check for setsockopt() failures
[1] This is why I'm nervous for this patch.
If we can confirm that --multihome works as expected on platforms without
IPV6_RECVPKTINFO, then I'm fine with this patch. Otherwise, we need to
figure out how to make --multihome work too.
JJO, please have a look at this.
kind regards
