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]namesArray that is used to return the supported dynamic flags names.
[in]nThe 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_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.
Returns
  • (0) if successful.
  • Negative value if an error.
