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 -----Original Message----- From: Stephen Hemminger [mailto:step...@networkplumber.org] Sent: Monday, October 12, 2015 6:39 PM To: Shaham Fridenberg Cc: dev at dpdk.org Subject: Re: [dpdk-dev] dpdk 2.1.0: 40gig ports link is down On Mon, 12 Oct 2015 13:29:42 +0000 Shaham Fridenberg <ShahamF at Radware.com> wrote: > 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).
