Function Documentation

__rte_experimental int rte_pmd_mlx5_get_dyn_flag_names	(	char *	names[],
		unsigned int	n
	)

Returns the dynamic flags name, that are supported.

Parameters

[out]	names	Array that is used to return the supported dynamic flags names.
[in]	n	The number of elements in the names array.

Returns

The number of dynamic flags that were copied if not negative. Otherwise:

• ENOMEM - not enough entries in the array
• EINVAL - invalid array entry

__rte_experimental int rte_pmd_mlx5_sync_flow	(	uint16_t	port_id,
		uint32_t	domains
	)

Synchronize the flows to make them take effort on hardware. It only supports DR flows now. For DV and Verbs flows, there is no need to call this function, and a success will return directly in case of Verbs.

Parameters

[in]	port_id	The port identifier of the Ethernet device.
[in]	domains	Refer to "/usr/include/infiniband/mlx5dv.h". Bitmask of domains in which the synchronization will be done. MLX5_DOMAIN_BIT* macros are used to specify the domains. An ADD or OR operation could be used to synchronize flows in more than one domain per call.

Returns

• (0) if successful.
• Negative value if an error.
