libeth_xdp_prepare_buff() *always* initializes xdp->data, so there's no
way that prefetch() will get NULL.

Yeah. Intel created the zero day bot before lei was invented. You
weren't supposed to recieve this email because we filter out the
obvious false postives and resend the others.
The zero day bot can't use the cross function database because it
doesn't scale well enough.
