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

[Shaham Fridenberg]

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

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).
