== 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

+
--
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
