I didn't accumulated other changes to these patches,
so they can be applied as is. If needed, I can submit the
ipvsadm patch again because I didn't sent a copy to Jesper.
In fact, we do not need to hurry with these patches, no problem
if we apply them after the next merge window. Lets give
some time, in case someone has idea for new attribute or
other changes for stats.
