Because both serve different purposes. (2)reserve several bits as input set selection from bottom of the 64 bits. It is combined with exisiting ETH_RSS_* to represent rss types. for example: ETH_RSS_IPV4 | ETH_RSS_L3_SRC_ONLY: hash on src ip address only ETH_RSS_IPV4_UDP | ETH_RSS_L4_DST_ONLY: hash on src/dst IP and dst UDP port ETH_RSS_L2_PAYLOAD | ETH_RSS_L2_DST_ONLY: hash on dst mac address Signed-off-by: Simei Su --- lib/librte_ethdev/rte_ethdev.h | 60 ++++++++++++++++++++++++------------------ 1 file changed, 35 insertions(+), 25 deletions(-) diff --git a/lib/librte_ethdev/rte_ethdev.h b/lib/librte_ethdev/rte_ethdev.h index d987178..7e6530d 100644 --- a/lib/librte_ethdev/rte_ethdev.h +++ b/lib/librte_ethdev/rte_ethdev.h @@ -482,31 +482,41 @@ struct rte_eth_rss_conf { #define RTE_ETH_FLOW_MAX 23 /* - * The RSS offload types are defined based on flow types. - * Different NIC hardware may support different RSS offload - * types.
