--- Comment #11 from Pablo Neira Ayuso <pablo at netfilter.org> ---
This affinity map also needs to deal with two packets racing to set up the
affinity?

         chain endpoint-1 {
                 counter packets 2 bytes 224
                 update @affinity-mappings { ip saddr : 11.0.2.2 } meta l4proto
tcp dnat to 11.0.2.2 : 5001
                 # lost race, re-lookup to use existing mapping
                 meta l4proto tcp dnat to ip saddr map @affinity-mappings :
5001
                 # not found, should not ever happen
                 counter drop
         }
