Typedef Documentation

typedef void*(* rte_port_in_op_create) (void *params, int socket_id)

Input port create

Parameters
paramsParameters for input port creation
socket_idCPU socket ID (e.g. for memory allocation purpose)
Returns
Handle to input port instance

Definition at line 71 of file rte_port.h.

typedef int(* rte_port_in_op_free) (void *port)

Input port free

Parameters
portHandle to input port instance
Returns
0 on success, error code otherwise

Definition at line 81 of file rte_port.h.

Input port packet burst RX

Parameters
portHandle to input port instance
pktsBurst of input packets
n_pktsNumber of packets in the input burst
Returns
0 on success, error code otherwise

Definition at line 95 of file rte_port.h.

typedef int(* rte_port_in_op_stats_read) (void *port, struct rte_port_in_stats *stats, int clear)

Input port stats get

Parameters
portHandle to output port instance
statsHandle to port_in stats struct to copy data
clearFlag indicating that stats should be cleared after read
Returns
Error code or 0 on success.

Definition at line 113 of file rte_port.h.

typedef void*(* rte_port_out_op_create) (void *params, int socket_id)

Output port create

Parameters
paramsParameters for output port creation
socket_idCPU socket ID (e.g. for memory allocation purpose)
Returns
Handle to output port instance

Definition at line 146 of file rte_port.h.

typedef int(* rte_port_out_op_free) (void *port)

Output port free

Parameters
portHandle to output port instance
Returns
0 on success, error code otherwise

Definition at line 156 of file rte_port.h.

typedef int(* rte_port_out_op_tx) (void *port, struct rte_mbuf *pkt)

Output port single packet TX

Parameters
portHandle to output port instance
pktInput packet
