Peter, unless you see a problem with that, this patch would be superseded by: [PATCH 2/3] fwd, pif: Replace with pif_sock_l4() with pif_listen() https://archives.passt.top/passt-dev/20260302043135.800803-3-david@gibson.dr... as it avoids the need for this static_assert() altogether. So I would drop this patch (carrying a Reported-by: tag) in favour of that one. -- Stefano
