[dpdk-dev] Link discovery using DPDK-based NICs

Hi all, I wonder if there is any means in DPDK to perform link discovery. I know that DPDK is all about packet I/O, but maybe there is some library with useful functions that an application could use for link discovery (e.g., using LLDP). Any suggestions are much appreciated. Thanks, -- Georgios

[dpdk-dev] Some flow rules not supported by igb_uio

Hi, I am testing rte flow API across different DPDK-based NICs using some rules. I noticed that flow rules that match L2 information, such as rule: flow create 0 ingress pattern eth type is 0x800 / end actions queue index 6 / end does not work on an Intel 82599ES (igb_uio driver), while a Mellan

Re: [dpdk-dev] [PATCH 1/3] app/testpmd: Moved cmdline_flow to librte_cmdline

Hi again, I decided to simplify things for now, hence sent a new minimal patch only for testpmd (not librte_cmdline), which allows external applications to compile against it without errors. Thanks again for you time, Georgios On Tue, Jan 16, 2018 at 6:54 PM, Adrien Mazarguil wrote: > On Tue, J

Re: [dpdk-dev] [PATCH 1/3] app/testpmd: Moved cmdline_flow to librte_cmdline

Hi Adrien, Thanks for your insights and sorry for omitting the cover letter (this is my first patch in DPDK). I understand your concerns. The reason I proposed this patch is to facilitate a more high level vendor agnostic API for configuring and monitoring DPDK-based NICs. To avoid just copying t

Re: [dpdk-dev] [PATCH 1/3] app/testpmd: Moved cmdline_flow to librte_cmdline

Hi Lu, Oliver, Thanks for your feedback! You have a point here, flow commands are only a subset of the parser. Do you want me to create this new library and send another patch? I guess I have to use librte_cmdline as a template/example for creating the librte_flow_cmdline library. Best regards, G

Hi Gaetan, Thanks for your quick and positive reply, I will submit a patch today. Best regards, Georgios On Fri, Jan 12, 2018 at 11:38 AM, Gaëtan Rivet wrote: > Hi George, > > On Fri, Jan 12, 2018 at 10:21:41AM +0100, george@gmail.com wrote: > > Dear DPDK developers, > > > > In an attempt

[dpdk-dev] Move flow parsing from test-pmd to librte_cmdline

Dear DPDK developers, In an attempt to integrate the Flow API into a third party application and allow the e.g., insertion/deletion of NIC classification rules from that application, I noticed that flow command parsing as per the most recent DPDK versions (i.e., 17.08 or 17.11) might benefit from

Hi Shahaf, Thanks for the clarification! Is there a plan for this functionality to be provided (soon)? (or any technical limitation that stands in this way) Thanks and best regards, Georgios On Mon, Jan 9, 2017 at 2:32 PM, Shahaf Shuler wrote: > Hi Georgios, > > It is not support on Mellanox P

[dpdk-dev] Port stats zero when using MLX5 DPDK driver

Hi, I have a simple setup with a machine that contains a dual port 10 GbE Intel 82599ES NIC and another dual port 100 GbE Mellanox ConnectX-4 NIC. The Intel ports are 0 and 1, while the Mellanox ones are 2 and 3. I properly compiled DPDK 16.11 and test-pmd works just fine for all 4 ports. Then, I

Re: [dpdk-dev] ConnectX4 100GbE - Compilation problem

Hi again, I have a follow up question. I noticed that when I compile DPDK with CONFIG_RTE_LIBRTE_MLX5_PMD=y, the compilation fate depends upon the OFED version that I have. To become more clear, with DPDK 16.11 and OFED 3.4-2.0.0.0 it compiles, but DPDK 16.07 and the same OFED fails with: == Buil

Re: [dpdk-dev] ConnectX4 100GbE - Compilation problem

Hi all, I am coming back to you regarding the Mellanox Connectx4 100Gbps DPDK driver. We exchanged some e-mails last summer and I managed to compile the DPDK-based Mellanox driver using DPDK 16.07 on top of Ubuntu server 16.04.01. A few days ago, I installed a fresh Ubuntu server 16.04.1 on my ma
