Comment 1 for bug 1439817

The default number of elements in an ipset set is only 64K, so it can be hit pretty easily during some test cycles (we've seen it at HP now obviously). As a quick fix we can make both the hashelem and hashsize values tunable, so that a larger size can be set. A better long-term solution might be to detect this failure and increase the size automatically.

I'll assign this to myself and get a quick patch out for discussion.
