== DESCRIPTION

*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

== OPTIONS

--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.

== EXAMPLES

To see program arguments:

    dpauxmon --help

To see program version:

    dpauxmon --version

To see interfaces:

    dpauxmon --extcap-interfaces

Only one interface (dpauxmon) is supported.

.Example output
    interface {value=dpauxmon}{display=DisplayPort AUX channel capture}

To see interface DLTs:

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

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

To see interface configuration options:

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

.Example output
    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
