examples/ip_fragmentation: overhaul
New stuff: * Support for regular traffic as well as IPv4 and IPv6 * Simplified config * Routing table printed out on start * Uses LPM/LPM6 for lookup * Unmatched traffic is sent to the originating port Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com> Tested-by: Waterman Cao <waterman.cao@intel.com> Acked-by: Thomas Monjalon <thomas.monjalon@6wind.com>
