dpauxmon is an extcap tool that can capture DisplayPort AUX channel data from linux kernel drivers using the generic netlink interface.
Supported interfaces:
1. dpauxmon
−−help
Print program arguments.
−−version
Print program version.
−−extcap−interfaces
List available interfaces.
−−extcap−interface=<interface>
Use specified interfaces.
−−extcap−dlts
List DLTs of specified interface.
−−extcap−config
List configuration options of specified interface.
−−capture
Start capturing from specified interface and save it in place specified by −−fifo.
−−fifo=<path to file or pipe>
Save captured packet to file or send it through pipe.
−−interface_idt=<interface id>
The interface for capture.

Example output
interface {value=dpauxmon}{display=DisplayPort AUX channel capture}
To see interface DLTs:
dpauxmon −−extcap−interface=dpauxmon −−extcap−dlts
Example output

To see interface configuration options:
dpauxmon −−extcap−interface=dpauxmon −−extcap−config
Example output
dpauxmon
−−extcap−interface=dpauxmon
−−extcap−config
