[PATCH v4 1/2] doc: updated incorrect value for IP frag max fragments

[Euan Bourke <euan.bourke@intel.com>]

Docs for IP Fragment said RTE_LIBRTE_IP_FRAG_MAX_FRAG was 4 by default,
however this was changed to 8.

Documentation has been updated to account for this, including a
snippet of code where RTE_LIBRTE_IP_FRAG_MAX_FRAG is defined to
ensure documentation stays up to date.

Fixes: f8e0f8ce9030 ("ip_frag: increase default maximum of fragments")
