Re: [dpdk-users] Intel 710 Series and multiple vlan tags

I should add that our ports are in promiscuous mode, and are not inline: we do not respond to stateful packets, only receive them. Thanks, Michal From: Dorsett, Michal Sent: Monday, January 01, 2018 2:24 PM To: users@dpdk.org Cc: Maimon, Royi Subject: Intel 710 Series and multiple vlan tags

[dpdk-users] Intel 710 Series and multiple vlan tags

Our application receives large amounts of very varied traffic. A single port may receive 'pure' ipv4 traffic, as well as traffic with 4 vlan layers, and MPLS traffic comprising 3 mpls labels. The nic has to be able to load balance all that traffic between 2 or more queues. According to the 710 S

[dpdk-users] Configuring IP RSS with an XL710 interface

Hi, I am injecting very versatile stateful traffic using Ixia Perfect Storm at ~18Gbps. The traffic has no tunnels. It has very simple IPv4+TCP/UDP over an Ethernet layer. I use 3 10Gbps ports out of the 4x10 for receiving traffic. Each port has 4 queues. When I configure the following: p

[dpdk-users] Round-robin instead of RSS

We are using an XL710 nic 4x10Gbps. Our application needs to delay all packets in the system for at least the first second, and depending on the type of traffic mbufs may need to delay packets even more. Since the XL710 makes use of, at most, 1M mbufs in a queue and not more - we need to create

[dpdk-users] rx-missed errors with the fortville nic

I would like your help in investigating a packet loss problem we have with an XL710 NIC split in 4x10 configuration and the X710: Issue: While injecting traffic to one of the NICs ports we noticed that not all packets are received by the application - rx_missed statistic is incrementing. HW Env

Hi, We are using DPDK 16.07. In the documentation for the libpmd_i40e I read the following explanation re. RTE_LIBRTE_I40E_ITR_INTERVAL: Due to the hardware design, the interrupt signal inside NIC is needed for per packet descriptor write-back. The minimum interval of interrupts could be set at

[dpdk-users] movzbl in rte_eth_rx_burst

Hi, We are running dpdk 16.07. Below is a snippet from a perf annotate report of a CPU running a thread that constantly reads packets. As you can see, the hottest instructruction is movzbl 0x10(%rcx),%r15d which, I believe, is referring to struct rte_eth_dev *dev = &rte_eth_devices[port_id];
