Signed-off-by: Helin Zhang --- lib/librte_ether/rte_ethdev.h | 1 + 1 file changed, 1 insertion(+) v2 changes: * Disabled the code changes by default, to avoid breaking ABI compatibility. v3 changes: * Moved the newly added element right after 'uint16_t reta_size', where it was a padding. So it will not break any ABI compatibility, and no need to disable it by default. diff --git a/lib/librte_ether/rte_ethdev.h b/lib/librte_ether/rte_ethdev.h index 16dbe00..bce152d 100644 --- a/lib/librte_ether/rte_ethdev.h +++ b/lib/librte_ether/rte_ethdev.h @@ -918,6 +918,7 @@ struct rte_eth_dev_info { uint32_t tx_offload_capa; /**< Device TX offload capabilities. */ uint16_t reta_size; /**< Device redirection table size, the total number of entries. */ + uint8_t hash_key_size; /**< Hash key size in bytes */ /** Bit mask of RSS offloads, the bit offset also means flow type */ uint64_t flow_type_rss_offloads; struct rte_eth_rxconf default_rxconf; /**< Default RX configuration */ -- 1.9.3
