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

       To see program arguments:

           dpauxmon --help

       To see program version:

           dpauxmon --version

       To see interfaces:

           dpauxmon --extcap-interfaces

       Only one interface (dpauxmon) is supported.

       Exampleoutput

           interface {value=dpauxmon}{display=DisplayPort AUX channel capture}

       To see interface DLTs:

           dpauxmon --extcap-interface=dpauxmon --extcap-dlts

       Exampleoutput

           dlt {number=275}{name=dpauxmon}{display=DisplayPort AUX channel monitor DLT}

       To see interface configuration options:

           dpauxmon --extcap-interface=dpauxmon --extcap-config

       Exampleoutput

           dpauxmon --extcap-interface=dpauxmon --extcap-config
           arg {number=0}{call=--interface_id}{display=Interface Id}
               {type=unsigned}{tooltip=The Interface Id}
               {required=true}

       To capture:

           dpauxmon --extcap-interface=dpauxmon --fifo=/tmp/dpauxmon.pcap --capture --interface_id 0
