SocketCAN replay

Trace replay lets you turn a capture into repeatable test evidence.

Use it for:

• compact trace fixtures
• bracketed candump fixtures
• malformed-line parser tests
• standard-ID rejection
• CAN FD token rejection in classic-only paths

Always record interface, bitrate, device list, command, and expected result.

Capture metadata

For a new trace, record:

• interface name, bitrate, and sample-point policy
• kernel/driver or adapter details
• connected devices and source addresses
• exact command used to capture
• expected accepted/rejected frame counts
• whether the trace is virtual CAN, bench hardware, or field capture
