We don't need a guarantee of stability, but what I am seeing is that
we're consisitently dropping entries on when doing a multi-part
netlink walk. We start iterating over the table filling in the netlink
info. But eventually the netlink info fills up and returns an error.
netlink dump gets called again but now the iter of the table returns
the object following the one that would have overflowed the netlink
buffer. So the result I was seeing is that we dropped one object in in
each pass.

Thanks Tom! This information is very useful.

It sounds like this problem isn't specific to ila and would exist
for all rhashtable users that dump through netlink.  Let me think
about this a little bit more.

Cheers,
