I've always been under the impression that mixing xtables and nftables
was impossible. Forgive me, but I just want to clarify one more time:
you're saying we should be able to modify iptables-nft such that the
following rule will use xt_bpf to match a packet and then nft_log to
log it, rather than xt_log as it does today?

    iptables-nft -A test-chain -d 11.22.33.44/32 -m bpf --bytecode
"1,6 0 0 65536" -j NFLOG --nflog-prefix
"0123456789012345678901234567890123456789012345678901234567890123456789"

We had some unexplained performance loss when we were evaluating
switching to iptables-nft, but if this sort of mixing is possible then
it is certainly worth reevaluating.
