[dpdk-dev] dpdk 2.1.0: 40gig ports link is down

[Shaham Fridenberg]

Hey all,

I upgraded from dpdk 1.8.0 to 2.1.0 and now my 40gig ports (rte_i40e_pmd) link is down.

Any idea what might be the issue?

Thanks,
Shaham

Compile i40e with DEBUG flag enabled in config and make sure LOGLEVEL
is set to 8 to show debug output.

It maybe something related to firmware versions.
Make sure you have updated firmware (see Intel tool).

Hey Stephen,

Thanks for your help.

I tried updating i40e driver to the latest version (from 1.0.11-k to 1.3.39.1) but it didn't help.

By 'Compile i40e with DEBUG flag' you mean adding "CONFIG_RTE_LOG_LEVEL=8" to defconfig_x86_64-wsm-linuxapp-gcc (assuming I'm compiling for westmere)?

Also, is there any log file generated in that case?

Thanks,
Shaham

I was thinking of firmware update tool, which you need to run on Linux (w/o DPDK)
 https://downloadcenter.intel.com/download/24769/NVM-Update-Utility-for-Intel-Ethernet-Converged-Network-Adapter-XL710-X710-Series

In current DPDK, the config stuff is in common_linuxapp

Updating the firmware using the tool did solve the problem! Now link is up.

Thanks a lot for your time and help Stephen! :)
