This RFC reserves several bits as input set selection from bottom of the 64 bits. The flow type is combined with input set to represent rss types. for example: ETH_RSS_IPV4 | ETH_RSS_INSET_L3_SRC: hash on src ip address only ETH_RSS_IPV4_UDP | ETH_RSS_INSET_L4_DST: hash on src/dst IP and dst UDP port ETH_RSS_L2_PAYLOAD | ETH_RSS_INSET_L2_DST: hash on dst mac address Signed-off-by: Simei Su --- lib/librte_ethdev/rte_ethdev.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/lib/librte_ethdev/rte_ethdev.h b/lib/librte_ethdev/rte_ethdev.h index dc6596b..8af6355 100644 --- a/lib/librte_ethdev/rte_ethdev.h +++ b/lib/librte_ethdev/rte_ethdev.h @@ -508,6 +508,19 @@ struct rte_eth_rss_conf { #define ETH_RSS_GENEVE (1ULL << RTE_ETH_FLOW_GENEVE) #define ETH_RSS_NVGRE (1ULL << RTE_ETH_FLOW_NVGRE) +/* + * The following six macros are used combined with ETH_RSS_* to + * represent rss types.
