Hi, I am using dpdk 2.1. I see the hash flags are unified compared to my previous version 1.8. But with DPDK 2.1 in Fortville NIC's, I see ipv6 RSS is not working, all the frames are queued to first queue even though I have 16 queues (RETA table looks correct).
For IPV4 RSS works as expected in Fortville. Also in 10G, both ipv4 and ipv6 RSS works. My RSS configuration is : rss_hf = ETH_RSS_IP | ETH_*RSS* _NONFRAG_IPV4_TCP | ETH_*RSS*_NONFRAG_IPV4_UDP I see ETH_RSS_IP contains Layer3 hash flags for ipv6. #define ETH_*RSS*_IP ( \ ETH_*RSS*_IPV4 | \ ETH_*RSS*_FRAG_IPV4 | \ ETH_*RSS*_NONFRAG_IPV4_OTHER | \ ETH_*RSS*_*IPV6* | \ ETH_*RSS*_FRAG_*IPV6* | \ ETH_*RSS*_NONFRAG_*IPV6*_OTHER | \ ETH_*RSS*_*IPV6*_EX) But when I query the hash flags, I get the value of 8888. I understand while configuring RSS HF in the 40G NIC, we mask the configured RSS HF with NIC specific mask flags before writing to NIC. But I am not sure after masking it is taking the flags for IPV6. The mask or I40E: I40E_*RSS*_OFFLOAD_ALL . I see this conatins the flags ETH_*RSS*_FRAG_*IPV6 & *ETH_*RSS*_NONFRAG_*IPV6*_OTHER. Are you aware of any such problems? Please let me know if you need more information. Thanks
