X-BeenThere: users@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK usage discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 20 Sep 2018 19:37:55 -0000 Hello DPDK users, I was struggling with the packet fragmentation, since the dpdk application(l3fwd, ip-fragmentation, ip-assemble) did not recognized the received packet as the ipv4 header. At first, I have crafted my own packets when sending ipv4 headers so I assumed that I was crafting the packets in a wrong way. So I have used DPDK-pktgen but dpdk-application (l3fwd, ip-fragmentation, ip-assemble) did not recognized the ipv4 header. As the last resort, I have tested the dpdk-testpmd, and found out this in the status info. --------------------------------------------------------- ----------------------- ********************* Infos for port 1 ********************* MAC address: E4:1D:2D:D9:CB:81 Driver name: net_mlx4 Connect to socket: 1 memory allocation on the socket: 1 Link status: up Link speed: 10000 Mbps Link duplex: full-duplex MTU: 1500 Promiscuous mode: enabled Allmulticast mode: disabled Maximum number of MAC addresses: 127 Maximum number of MAC addresses of hash filtering: 0 VLAN offload: strip on filter on qinq(extend) off No flow type is supported.

Or is there additional configuration that needs to be done?
