Other boolean values are supposed to be accurate: - duplex mode (half/full) - negotiation (auto/fixed) This API update is making explicit that the link speed information is optional. The value ETH_SPEED_NUM_NONE (0) was already part of the API. The value ETH_SPEED_NUM_UNKNOWN (infinite) is added to cover two different cases: - speed is not known by the driver - device is virtual Suggested-by: Morten Brørup Suggested-by: Benoit Ganne Signed-off-by: Thomas Monjalon Reviewed-by: Ferruh Yigit --- lib/librte_ethdev/rte_ethdev.h | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/lib/librte_ethdev/rte_ethdev.h b/lib/librte_ethdev/rte_ethdev.h index a49242bcd..2090af501 100644 --- a/lib/librte_ethdev/rte_ethdev.h +++ b/lib/librte_ethdev/rte_ethdev.h @@ -303,6 +303,7 @@ struct rte_eth_stats { #define ETH_SPEED_NUM_56G 56000 /**< 56 Gbps */ #define ETH_SPEED_NUM_100G 100000 /**< 100 Gbps */ #define ETH_SPEED_NUM_200G 200000 /**< 200 Gbps */ +#define ETH_SPEED_NUM_UNKNOWN UINT32_MAX /**< Unknown */ /** * A structure used to retrieve link-level information of an Ethernet port. @@ -2262,15 +2263,16 @@ int rte_eth_allmulticast_disable(uint16_t port_id); int rte_eth_allmulticast_get(uint16_t port_id); /** - * Retrieve the status (ON/OFF), the speed (in Mbps) and the mode (HALF-DUPLEX - * or FULL-DUPLEX) of the physical link of an Ethernet device.
