[dpdk-users] Not able to receive packet via api rte_eth_rx_burst

I have modified rxtx_callback example to just receive on single port. However it is not working rte_eth_stats_get() shows packets are present in ethernet ring via the field ipackets but rte_eth_rx_burst is not returning any packets. Code is included here, please let me know what I am doing wrong.

[dpdk-users] Bring DPDK on ConnectX-3

Hi， Recently I have worked on running dpdk on our infiniband card but failed. Our adapters card is ConnectX-3, which is in the dpdk’s support hardwares list, but specific type, MSX6710-FS2F2 is not found in detailed support nics list of mlx4. Environment Adapter card: Mellanox MSX6710-FS2F2

Re: [dpdk-users] Failed to allocate tx pool

Hi Cliff, Yes, I had tried it. When I set memory on both NUMA nodes it works without this issue. I set using the following commands: root@rg2-14053:/home/adara/raghu_2/dpdk-2.2.0# echo 128 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages

Re: [dpdk-users] Ideal design to use ip-fragmentation using multiple lcores

Thank you very much for the reply, this cleared things up. So in that case, I need a single frag-table correct? so If I want to receive using multiple rx-queues, the fragmented data can arrive at different queues, which means I cannot have multiple frag-table. And does this imply that I have to

Re: [dpdk-users] Failed to allocate tx pool

Hi Cliff, But I want to allocate memory on only NUMA node where my lcore's and DPDK NICs are connected. I think this gives the most optimized performace when everything is connected to the same NUMA node. Thanks, Raghu -Original Message- From: Raghu Gangi Sent: Wednesday, October 31,

Re: [dpdk-users] Bring DPDK on ConnectX-3

Hi Quan Not all mlx4 devices are supported by DPDK. What does "lspc -n" how on your host ? This can help in order to see if your device is supported by DPDK . Regards, Rami Rosen בתאריך יום ד׳, 31 באוק׳ 2018, 19:19, מאת : > Hi， > > Recently I have worked on running dpdk on our infiniband card

Re: [dpdk-users] Bring DPDK on ConnectX-3

HI Quan, Your NIC is configured to use InfiniBand protocol. InfiniBand is not supported with DPDK , we have it in plans but not with ConnectX-3. Try to change it to ETH and check if works. In general we recommend to use ConnectX-3 Pro at least. Please follow instructions from dpdk.org

[dpdk-users] Possibly wrong RX statistics reported by virtio driver (TRex generator)

Hi list, The TRex traffic generator's folks recommended us to contact you for an issue that might relate to DPDK virtio driver (https://groups.google.com/forum/#!topic/trex-tgn/LxtTV7G43AE). Specifically, our scenario involves running TRex inside a KVM instance with 2 vhost-user ports,
