Initialize packet capturing handling

Register the IPC action for communication with target (primary) process.

Returns

Un initialize packet capturing handling

Unregister the IPC action for communication with target (primary) process.

Returns

Enables packet capturing on given port and queue.

Parameters

port port on which packet capturing should be enabled.
queue queue of a given port on which packet capturing should be enabled. users should pass on value UINT16_MAX to enable packet capturing on all queues of a given port.
flags flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.
ring ring on which captured packets will be enqueued for user.
mp mempool on to which original packets will be mirrored or duplicated.
filter Unused should be NULL.

Returns

Enables packet capturing on given port and queue with filtering.

Parameters

port_id The Ethernet port on which packet capturing should be enabled.
queue The queue on the Ethernet port which packet capturing should be enabled. Pass UINT16_MAX to enable packet capturing on all queues of a given port.
flags Pdump library flags that specify direction and packet format.
snaplen The upper limit on bytes to copy. Passing UINT32_MAX means capture all the possible data.
ring The ring on which captured packets will be enqueued for user.
mp The mempool on to which original packets will be mirrored or duplicated.
prm Use BPF program to run to filter packes (can be NULL)

Returns

Disables packet capturing on given port and queue.

Parameters

port port on which packet capturing should be disabled.
queue queue of a given port on which packet capturing should be disabled. users should pass on value UINT16_MAX to disable packet capturing on all queues of a given port.
flags flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.

Returns

Enables packet capturing on given device id and queue. device_id can be name or pci address of device.

Parameters

device_id device id on which packet capturing should be enabled.
queue queue of a given device id on which packet capturing should be enabled. users should pass on value UINT16_MAX to enable packet capturing on all queues of a given device id.
flags flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.
ring ring on which captured packets will be enqueued for user.
mp mempool on to which original packets will be mirrored or duplicated.
filter unused should be NULL

Returns

Enables packet capturing on given device id and queue with filtering. device_id can be name or pci address of device.

Parameters

device_id device id on which packet capturing should be enabled.
queue The queue on the Ethernet port which packet capturing should be enabled. Pass UINT16_MAX to enable packet capturing on all queues of a given port.
flags Pdump library flags that specify direction and packet format.
snaplen The upper limit on bytes to copy. Passing UINT32_MAX means capture all the possible data.
ring The ring on which captured packets will be enqueued for user.
mp The mempool on to which original packets will be mirrored or duplicated.
filter Use BPF program to run to filter packes (can be NULL)

Returns

Disables packet capturing on given device_id and queue. device_id can be name or pci address of device.

Parameters

device_id pci address or name of the device on which packet capturing should be disabled.
queue queue of a given device on which packet capturing should be disabled. users should pass on value UINT16_MAX to disable packet capturing on all queues of a given device id.
flags flags specifies RTE_PDUMP_FLAG_RX/RTE_PDUMP_FLAG_TX/RTE_PDUMP_FLAG_RXTX on which packet capturing should be enabled for a given port and queue.

Returns

Retrieve the packet capture statistics for a queue.

Parameters

port_id The port identifier of the Ethernet device.
stats A pointer to structure of type rte_pdump_stats to be filled in.

Returns

Zero if successful. -1 on error and rte_errno is set.
