Hello,
   Our application needs symmetric hashing to handle the reverse traffic on the same core, also to
Improve performance by distributing the traffic across core.
Tried using rss config as below .
action_rss_tcp.types = ETH_RSS_NONFRAG_IPV4_TCP | ETH_RSS_L3_SRC_ONLY| ETH_RSS_L3_DST_ONLY | ETH_RSS_L4_SRC_ONLY | ETH_RSS_L4_DST_ONLY;
but could not get desired result.
Is there any options or API available to enable symmetric RSS hashing .
We are using dpdk 20.11 and intel NIC X710 10GbE .

Regards,
Bala
