Add an area after the xdp_buff in struct xdp_buff_xsk that drivers can use to stash extra information to use in metadata kfuncs. The maximum size of 24 bytes means the full xdp_buff_xsk structure will take up exactly two cache lines (with the cb field spanning both). Also add a macro drivers can use to check their own wrapping structs against the available size.
