> Subject: [PATCH] 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")
