Key Features

• Consolidated Napatech Flow Manager support (now with periodic flow updates)
• Flow tracking on NVIDIA DOCA Flow CT (BlueField 3 and ConnectX 6/7)

PF_RING Library

• Add PF_RING_FLOW_UPDATE_CAUSE_PERIODIC to generic flow offload messages
• Add support for Arista 7280 timestamps
• Add ifindex to interface list returned by pfring_findalldevs()
• Add PF_RING_HW_TIMESTAMP_UNSYNC flag to avoid setting the hw clock using system time (e.g. when using PTP)

PF_RING Kernel Module

• Set interface name under /proc for non-kernel devices
• Add SO_GET_CLUSTER_OBJECT_INFO to read ZC queue status

ZC Library

• New API calls to check if a queue is locked and in use (pfring_zc_ipc_queue_in_use, pfring_zc_ipc_queue_in_use_from_cluster, pfring_zc_ipc_queue_in_use_from_queue)
• Add pfring_zc_get_num_rx_channels API (print number of device queue in zcount and zbalance_ipc)
• Implemented GTPv0 balancing in built-in hash
• Add PF_RING_ZC_DEVICE_HW_TIMESTAMP_UNSYNC flag to avoid setting the hw clock using system time (e.g. when using PTP)

FT Library

• Add PFRING_FT_TABLE_FLAGS_NO_GUESS flag to disable protocol guess
• Add PFRING_FT_IGNORE_VLAN to ignore VLAN in flow key
• Add action to pfring_ft_packet_metadata to be used in packet callbacks
• Fix flow slices export (duration)
• Fix shunting

PF_RING Capture Modules and ZC Drivers

• Napatech improvements
  • Add support for periodic flow updates with the latest Flow Manager API
  • Add support for NT_TIMESTAMP_TYPE_UNIX_NANOTIME
  • Handle PF_RING_FLOW_OFFLOAD_NOUPDATES to disable periodic updates
  • Fix flow ID (32-bit on API v2) on new Flow Manager API
• NVIDIA (Mellanox) ConnectX improvements
  • RSS limit set to 64 queues
  • Add PF_RING_RSS env var to set number of rss queues (rather then reading system conf)
  • Fix BPF rules
• Intel improvements

  • Add -f to ftflow. Update FT libs.
  • Fix uninitialized memory and minor leaks
• ftflow_pcap
  • Add -N option to disable L7 protocol guess
• pfflow_offload improvements for Napatech Flow Manager
  • Add -u to enable periodic updates

Misc

• Add ARM support for PF_RING FT
