What does the phrase "consider native interface" refer to when the nftables wiki says that xt_bpf match is unsupported

In [this](https://wiki.nftables.org/wiki-nftables/index.php/Supported_features_compared_to_xtables) list of unsupported xtables features. xt_bpf is listed as one of the unsupported features. The comment says to "consider native interface". But what interface is being referred to here? This is the only ever mention of bpf in the entire nftables wiki.
