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

[Euan Bourke]

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

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