In particular, I bump into this error when invoking the rte_eth_dev_configure function: PMD: librte_pmd_mlx4: 0x10a4d2a0: TX queues number update: 0 -> 16 PMD: librte_pmd_mlx4: 0x10a4d2a0: RX queues number update: 0 -> 16 PMD: librte_pmd_mlx4: 0x10a4d2a0: only a single RX queue can be configured when hardware doesn't support RSS On the other hand, it seems that my hardware is configured to have 16 RX/TX queues (equal to the number of cores) $ ethtool -l p785p1 Channel parameters for p785p1: Pre-set maximums: RX: 128 TX: 32 Other: 0 Combined: 0 Current hardware settings: RX: 16 TX: 16 Other: 0 Combined: 0 ------ Additional info I am using DPDK 2.2 I have followed the instructions in [1] to install MLNX_OFED_LINUX-3.1-1.0.3-ubuntu14.04-x86_64 (3.2 is out, but instructions in [1] refers to 3.1) My NIC : 05:00.0 Ethernet controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro] My machine runs a 3.19.0-47-generic on Ubuntu 14.04. CPU is Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz 2x8 cores ------ Note that, in the end, the software I am going to use is intended to use flow director and not RSS. Any idea? I have the feeling the solution might be trivial, but I am a noob in this domain and I have searched around, finding no answer. Thank you --Harold [1] http://dpdk.org/doc/guides/nics/mlx4.html
