The following patchset contains Netfilter fixes for *net*: 1) I managed to add a null dereference crash in nft_set_pipapo in the current development cycle, was not caught by CI because the avx2 implementation is fine, but selftest splats when run on non-avx2 host. 2) Fix the ipvs estimater kthread affinity, was incorrect since 6.14. From Frederic Weisbecker. 3) nf_tables should not allow to add a device to a flowtable or netdev chain more than once -- reject this. From Pablo Neira Ayuso. This has been broken for long time, blamed commit dates from v5.8.
