Limitations

• Using multiple onload_tcpdump instances to capture from the same onload stack is not a supported configuration.
• Currently onload_tcpdump captures only packets from Onload stacks and not from kernel stacks.
• onload_tcpdump delivers timestamps with microsecond resolution. onload_tcpdump does not support nanosecond precision.
• The onload_tcpdump application monitors stack creation events and will attach to newly created stacks however, there is a short period (normally only a few milliseconds) between stack creation and the attachment during which packets sent/received will not be captured.
