> > 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
