We can give an testpmd command line example to make it more clear. For example, below flow selects the l4 port as inputset for any eth/ipv4/tcp packet: #flow create 0 ingress pattern eth / ipv4 / tcp / end actions rss inputset tcp src mask 0xffff dst mask 0xffff /end Signed-off-by: Simei Su --- lib/librte_ethdev/rte_flow.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/lib/librte_ethdev/rte_flow.h b/lib/librte_ethdev/rte_flow.h index f3a8fb1..2a455b6 100644 --- a/lib/librte_ethdev/rte_flow.h +++ b/lib/librte_ethdev/rte_flow.h @@ -1796,6 +1796,9 @@ struct rte_flow_action_rss { uint32_t queue_num; /**< Number of entries in @p queue. */ const uint8_t *key; /**< Hash key. */ const uint16_t *queue; /**< Queue indices to use. */ + struct rte_flow_item *inputset; /** Provide more specific inputset configuration. + * ignore spec, only mask. + */ }; /**
