RTE Port
This tool is part of the Intel DPDK Packet Framework tool suite and provides a standard interface to implement different types of packet ports.
#define RTE_PORT_IN_BURST_SIZE_MAX 64 |
Maximum number of packets read from any input port in a single burst.
Cannot be changed.
typedef void*(* rte_port_in_op_create)(void *params, int socket_id) |
Input port create
params | Parameters for input port creation |
socket_id | CPU socket ID (e.g. for memory allocation purpose) |
typedef int(* rte_port_in_op_free)(void *port) |
Input port free
port | Handle to input port instance |
typedef int(* rte_port_in_op_rx)(void *port, struct rte_mbuf **pkts, uint32_t n_pkts) |
Input port packet burst RX
port | Handle to input port instance |
pkts | Burst of input packets |
n_pkts | Number of packets in the input burst |
typedef void*(* rte_port_out_op_create)(void *params, int socket_id) |
Output port create
params | Parameters for output port creation |
socket_id | CPU socket ID (e.g. for memory allocation purpose) |
typedef int(* rte_port_out_op_flush)(void *port) |
Output port flush
port | Handle to output port instance |
typedef int(* rte_port_out_op_free)(void *port) |
Output port free
port | Handle to output port instance |
typedef int(* rte_port_out_op_tx)(void *port, struct rte_mbuf *pkt) |
Output port single packet TX
port | Handle to output port instance |
pkt | Input packet |
typedef int(* rte_port_out_op_tx_bulk)(void *port, struct rte_mbuf **pkt, uint64_t pkts_mask) |
Output port packet burst TX
port | Handle to output port instance |
pkts | Burst of input packets specified as array of up to 64 pointers to struct rte_mbuf |
pkts_mask | 64-bit bitmask specifying which packets in the input burst are valid. When pkts_mask bit n is set, then element n of pkts array is pointing to a valid packet. Otherwise, element n of pkts array will not be accessed. |
