examples/ip_fragmentation: fix check of packet type
The packet_type in mbuf is not correctly filled by ixgbe 82599 NIC. To use the ether_type in ethernet header to check packet type is more reliaber. Fixes: 3c0184cc0c60 ("examples: replace some offload flags with packet type") Fixes: ab351fe1c95c ("mbuf: remove packet type from offload flags") Cc: stable@dpdk.org Reported-by: Fangfang Wei <fangfangx.wei@intel.com> Signed-off-by: Wei Dai <wei.dai@intel.com> Tested-by: Fangfang Wei <fangfangx.wei@intel.com> Acked-by: Konstantin Ananyev <konstantin.ananyev@intel.com>
