[dpdk-dev] Question about ip fragment library

Hi,all: Recently, I am reading source code about ipv4 fragment in DPDK 1.7.0. I am confused about ip packet with options. it seems that DPDK ip frag lib would omit all options from all fragments except the first one. However, in my opinion, some options must be present in all fragments,

Tested by Zhan, Zhaochen Applying these patches on the dpdk-1.7.0, we verified the compilation on FreeBSD10.0 with Clang 3.3 and Fedora20 with Clang 3.4. We also verified some simple test case (pmd, cmdline, hello_world and timer) on FreeBSD with Clang 3.3. > -Original Message- > From:

[dpdk-dev] DPDK Performance issue with l2fwd

Hey Guys, Recently, I have used l2fwd to test 160G (82599 10G * 16 ports), but I got a strange pheromone in my test. When I used 12 ports to test the performance of l2fwd, it can work fine and achieve 120G. But it got abnormal when I using over than 12 port. Part of ports seems something wrong an

[dpdk-dev] DPDK Performance issue with l2fwd

Hi Zachary, Your issue may be with the PCI-e 3, with 16 lanes Each slot is limited to 128Gb/s[3]. Now, AFAIK[1] the CPU is connected to the I/O with a single PCI-E slot. Several thoughts that may help you: 1. You can figure out the max b/w by running netsurf over the kernel interfaces (w/o DPDK)

[dpdk-dev] DPDK Performance issue with l2fwd

Hi Alex: Thanks for your help. I forget to describe some criteria in my original post. At first, I has confirmed my 82599 has connected by PCIe Gen3 (Gen3 x8) speed. The theoretical bandwidth can support over 160G in total. Hence, It should get full speed in my test. Second, I have ever check

[dpdk-dev] [PATCH] librte_pmd_packet: add PMD for AF_PACKET-based virtual devices

This is a Linux-specific virtual PMD driver backed by an AF_PACKET socket. This implementation uses mmap'ed ring buffers to limit copying and user/kernel transitions. The PACKET_FANOUT_HASH behavior of AF_PACKET is used for frame reception. In the current implementation, Tx and Rx queues are alw

Actually I did not build the kernel. It is unmodified from the original centos download. I also did not change any build parameters while building the module. Used all the defaults from the download and executed the commands as in the quick start guide. Is there something I can change and rebuild

[dpdk-dev] DPDK with Ubuntu 14.04?

Hey Folks, I know that official support hasn't moved past Ubuntu 12.04 LTS yet, but does anybody have any practical experience running with 14.04 LTS? My team has run into one compilation error so far with 1.7, but other than that things look OK at first blush. I'd like to move my product to 14.
