Enumeration Type Documentation enum rte_pmd_dlb2_token_pop_mode Warning EXPERIMENTAL: these enums may change, or be removed, without prior notice Selects the token pop mode for a DLB2 port. Definition at line 52 of file rte_pmd_dlb2.h. Function Documentation __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 __rte_experimental int rte_pmd_dlb2_set_port_param (uint8_t dev_id, uint8_t port_id, uint64_t flags, struct rte_pmd_dlb2_port_param * val) Warning EXPERIMENTAL: this API may change, or be removed, without prior notice Configure various port parameters. This function must be called before calling rte_event_port_setup() for the port, and after calling rte_event_dev_configure(). Parameters dev_id The identifier of the event device. port_id The identifier of the event port. flags Bitmask of the parameters being set. val Structure containing the values of parameters being set. Returns • 0: Success • EINVAL: Invalid dev_id, port_id, or mode • EINVAL: The DLB2 is not configured, is already running, or the port is already setup Author Generated automatically by Doxygen for DPDK from the source code.
