Function Documentation

TAILQ_HEAD	(	rte_driver_list	,
		rte_driver
	)

Double linked list of device drivers.

Examples:

ip_pipeline/pipeline/pipeline_firewall.c, ip_pipeline/pipeline/pipeline_flow_classification.c, and ip_pipeline/pipeline/pipeline_routing.c.

void rte_eal_driver_register

(

struct rte_driver *

driver

)

Register a device driver.

Parameters

driver

A pointer to a rte_dev structure describing the driver to be registered.

void rte_eal_driver_unregister

(

struct rte_driver *

driver

)

Unregister a device driver.

Parameters

driver

A pointer to a rte_dev structure describing the driver to be unregistered.

int rte_eal_dev_init

(

void

)

Initalize all the registered drivers in this process

int rte_eal_vdev_init	(	const char *	name,
		const char *	args
	)

Initialize a driver specified by name.

Parameters

name	The pointer to a driver name to be initialized.
args	The pointer to arguments used by driver initialization.

Returns

0 on success, negative on error

Examples:

l2fwd-crypto/main.c.

int rte_eal_vdev_uninit

(

const char *

name

)

Uninitalize a driver specified by name.

Parameters

name	The pointer to a driver name to be initialized.

Returns

0 on success, negative on error
