> Subject: [PATCH] ip_frag: fix ipv6 when MTU sizes not aligned to 8 bytes
>
> From: Chas Williams <[email protected]>
>
> The same issue was fixed on for the ipv4 version of this routine in
> commit 8d4d3a4f7337 ("ip_frag: handle MTU sizes not aligned to 8 bytes").
> Briefly, the size of an ipv6 header is always 40 bytes. With an MTU of
> 1500, this will never produce a multiple of 8 bytes for the frag_size
> and this routine can never succeed. Since RTE_ASSERTS are disabled by
> default, this failure is tpyically ignored.
>
> To fix this, round down to the nearest 8 bytes and use this when
> producing the fragments.
