> +* **ip_frag: changed handling of malformed fragments.**
> +
> +  - Duplicate fragments are tolerated instead of failing reassembly.
> +  - Overlapping fragments are rejected on arrival rather than during reassembly.
> +  - Oversized fragments (reassembled length over 65535) are rejected.
> +  - For IPv6, fragments with per-fragment extension headers are rejected.
> +
> +  Overlap and oversize are now detected on arrival, which adds a scan of the
> +  already received fragments per fragment and may affect throughput.
