Function Documentation

rte_pmd_dlb2_set_token_pop_mode()

__rte_experimental int rte_pmd_dlb2_set_token_pop_mode	(	uint8_t	dev_id,
		uint8_t	port_id,
		enum rte_pmd_dlb2_token_pop_mode	mode
	)

Warning

EXPERIMENTAL: this API may change, or be removed, without prior notice

Configure the token pop mode for a DLB2 port. By default, all ports use RTE_PMD_DLB2_AUTO_POP. This function must be called before calling rte_event_port_setup() for the port, but after calling rte_event_dev_configure().

Parameters

dev_id	The identifier of the event device.
port_id	The identifier of the event port.
mode	The token pop mode.

Returns

• 0: Success
• EINVAL: Invalid parameter dev_id, port_id, or mode
• EINVAL: The DLB2 device is not configured or is already running, or the port is already setup
