Function Documentation

◆ rte_pmd_mlx5_get_dyn_flag_names()

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

Returns the dynamic flags name, that are supported.

[out]namesArray that is used to return the supported dynamic flags names.
[in]nThe number of elements in the names array.
The number of dynamic flags that were copied if not negative. Otherwise:
  • ENOMEM - not enough entries in the array
  • EINVAL - invalid array entry

◆ rte_pmd_mlx5_sync_flow()

__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.

[in]port_idThe port identifier of the Ethernet device.
[in]domainsRefer 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.
  • (0) if successful.
  • Negative value if an error.
