Create memzone for HW rings. malloc can't be used as the physical address is needed. If the memzone is already created, then this function returns a ptr to the old one.
- Parameters
-
| eth_dev | The eth_dev pointer is the address of the rte_eth_dev structure |
| name | The name of the memory zone |
| queue_id | The index of the queue to add to name |
| size | The sizeof of the memory area |
| align | Alignment for resulting memzone. Must be a power of 2. |
| socket_id | The socket_id argument is the socket identifier in case of NUMA. |

- Warning
- EXPERIMENTAL: this API may change without prior notice.
Allocate an unique switch domain identifier.
A pool of switch domain identifiers which can be allocated on request. This will enabled devices which support the concept of switch domains to request a switch domain id which is guaranteed to be unique from other devices running in the same process.
- Parameters
-
| domain_id | switch domain identifier parameter to pass back to application |
- Returns
- Negative errno value on error, 0 on success.
| int __rte_experimental rte_eth_switch_domain_free |
( |
uint16_t |
domain_id | ) |
|
- Warning
- EXPERIMENTAL: this API may change without prior notice.
Free switch domain.
Return a switch domain identifier to the pool of free identifiers after it is no longer in use by device.
- Parameters
-
| domain_id | switch domain identifier to free |
- Returns
- Negative errno value on error, 0 on success.

PMD helper function to parse ethdev arguments
- Parameters
-
| devargs | device arguments |
| eth_devargs | parsed ethdev specific arguments. |
- Returns
- Negative errno value on error, 0 on success.

- Warning
- EXPERIMENTAL: this API may change without prior notice.
PMD helper function for the creation of a new ethdev ports.
- Parameters
-
| device | rte_device handle. |
| name | port name. |
| priv_data_size | size of private data required for port. |
| bus_specific_init | port bus specific initialisation callback function |
| bus_init_params | port bus specific initialisation parameters |
| ethdev_init | device specific port initialization callback function |
| init_params | port initialisation parameters |
- Returns
- Negative errno value on error, 0 on success.

|
) |
| |
- Warning
- EXPERIMENTAL: this API may change without prior notice.
PMD helper function for cleaing up the resources of a ethdev port on it's destruction.
- Parameters
-
| ethdev | ethdev handle of port. |
| ethdev_uninit | device specific port un-initialise callback function |
- Returns
- Negative errno value on error, 0 on success.
