Hi all, I forgot to tell you I work on Linux Debian 8. I set .rss_hf value to 0x7ef8 and now I see packets but:
I get an error message: *i40e_dev_alarm_handler(): ICR0: HMC error* I found here https://mails.dpdk.org/archives/dev/2018-September/111338.html that I am in the following case: + if (icr0 & I40E_PFINT_ICR0_HMC_ERR_MASK) + PMD_DRV_LOG(ERR, "ICR0: HMC error"); Does anyone know what goes wrong ? Additionally, I get many RX errors: Port RX pkt RX byte TX pkt TX byte RX error TX error 1 3290 5196839 0 0 62001 0 Queue RX pkt RX byte TX pkt TX byte RX error TX error 0 0 0 0 0 0 0 1 0 0 0 0 0 0 Thank you for your help, Ikuzar Le lun. 28 janv. 2019 à 18:02, ikuzar RABE <ikuzar9...@gmail.com> a écrit : > Hi all, > > I work with DPDK LTS version 18.11 to read packets from XL710-QDA2 with > configuration 2x40 > So there are 2 ports: port 0 and port 1.
