[dpdk-users] RSS in X710 NIC
Hello all, I am trying to operate RSS in X710 NIC. In order to do so, I use l3fwd example. I added a printf in l3fwd_lpm.c, right after rte_eth_rx_burst to print the lcore, queueid and nb_rx. In my server I have 2 NICs. X520 and X710. From each NIC I connect to a switch, and another connection to another server running pktgen, with range DST IPs. I operate with this cmdline: ./build/l3fwd -c f -n 1 -w -- -P -p 1 -config "(0,0,1),(0,1,2)" Where is either a port from X520 NIC or the X710 one. With X520 (using ixgbe), I see packets on both queues (0,1). With X710 (using i40e) I see packets always on queue 0. Though there is a message that I'd expect it should work. PMD: i40e_pf_config_rss(): Max of contiguous 2 PF queues are configured I use DPDK 16.07. Also tried 16.11 (and had to add -parse-ptype flag). Please advise.

[dpdk-users] issues with running ip_pipeline sample application
I also encountered the same issue. It seems the NIC doesn't report it's up fast enough for that code. For me it sometimes worked and sometimes didn't. I just pushed a sleep command before checking it's up (before calling to app_ports_check_link, in init.c). - This email and any files transmitted and/or attachments with it are confidential and proprietary information of Toga Networks Ltd., and intended solely for the use of the individual or entity to whom they are addressed.
