18 Cooked Mode Capture
21 If capturing is enabled and configured, the system will automatically capture
22 network traffic for a given network interface. If you would like to capture
24 the cooked mode capture API.
26 In cooked mode capture, arbitrary network packets can be captured and there
29 using the normal network interface based capture. Also CANBUS or Bluetooth
31 network stack to capture those.
33 The cooked mode capture works like this:
36 mode captured packets are written by the cooked mode capture API.
