<pre>Hit this one today. I've nothing to add to the thorough bug report, which
describes the behavior I observed to a tee.
Comments on workarounds:
1: Can confirm that removing auto-merge fixed the problem in my case as well.
2: Flushing the set in a separate call to nft prior to re-populating it loses
atomicity of the combined operation. If the set is used as an ACL (likely, as
this is a firewall after all), the brief time interval during which the set is
empty can result in unintended network access (or unintended blocking of such
access).</pre>
