Re: [dpdk-users] MLX5 build errors with DPDK 17.11.3

2018-08-06 Thread Wu, Xiaoban 
Hi Morgan,


It only installs the Mellanox OFED drivers. Then, you have to install the DPDK 
separately as usual.


I don't know in detail the purpose of the long options passed to the command.


Best wishes,

Xiaoban

Hi XiaoBan:

I have not tried it and I have some questions about it.

What does "--updteam-libs --dpdk" actually install? Does it install latest and 
greatest DPDK compatible OFED drivers or it actually installs both ofed drivers 
and Mellanox's modified DPDK?

If i run that command, do I still have to build the drivers from mainline 17.11 
DPDK?

Much Thanks
Morgan Yang

Hi Morgan,


Have you tried reinstallation of the latest "mlnxofed" by "./mlnxofedinstall 
--upstream-libs --dpdk"?


Best wishes,

Subject: [dpdk-users] MLX5 build errors with DPDK 17.11.3

Hi All:

I'm trying to build DPDK 17.11.3 with MLX5 (MCX456A-ECA). I have been using
Mellanox packaged DPDK packages (most recent MLNX DPDK 16.11
https://community.mellanox.com/docs/DOC-1502) with no issues. My
understanding is Mellanox is no longer packaging their own DPDK and
mainline DPDK should work.

I did enable " CONFIG_RTE_LIBRTE_MLX5_PMD=y" and
"CONFIG_RTE_TEST_PMD_RECORD_CORE_CYCLES=y".

However, I get tons of errors when I run "make install -j
T=x86_64-native-linuxapp-gcc"

I'm doing this from ubuntu 16.04, has anyone run into this issue before and
was able to build MLX5 drivers on Ubuntu 16.04?

Attached are the build errors

Much Thanks
Morgan Yang

Re: [dpdk-users] Drop_Packet

2018-08-06 Thread Andrew Bainbridge 
That's quite a broad question. A simple way is to not process packets you 
receive with rte_eth_rx_burst()! If you want the hardware to drop without the 
CPU seeing the packet, maybe you can setup a flow rule with a drop action. See 
https://doc.dpdk.org/guides/prog_guide/rte_flow.html.
