[dpdk-users] RSS Support in SRIOV (IXGBEVF X540)

[Geethu Joseph]

Hi, 








Iam using Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 with SRIOV enabled and created 32 VFs. I believe this will give 4 RX and 4 TX queues per VF. In the host PF I have enabled MQ mode and RSS is set with 4. 




In my guest(Centos) am running DPDK based application with single VF, 4 cores and 4 (rx,tx) queues. But packets are distributed only in the single core. In DPDK application I have set rss_hf as ETH_RSS_PROTO_MASK and mq_mode is set to ETH_MQ_RX_RSS. App is reading from all the 4 queues. But only queue 0 is getting packets. 



How can I enable distribution of packets into all the 4 queues in ixgbevf.
