=head1 DESCRIPTION
B<dpauxmon> is an extcap tool that can capture DisplayPort AUX channel data
from linux kernel drivers using the generic netlink interface.
Supported interfaces:
=over 4
=item 1. dpauxmon
=back
=head1 OPTIONS
=over 4
=item --help
Print program arguments.
=item --version
Print program version.
=item --extcap-interfaces
List available interfaces.
=item --extcap-interface=E<lt>interfaceE<gt>
Use specified interfaces.
=item --extcap-dlts
List DLTs of specified interface.
=item --extcap-config
List configuration options of specified interface.
=item --capture
Start capturing from specified interface and save it in place specified by --fifo.
=item --fifo=E<lt>path to file or pipeE<gt>
Save captured packet to file or send it through pipe.
=item --interface_idt=E<lt>interface idE<gt>
The interface for capture.
=back
=head1 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.
Output:
interface {value=dpauxmon}{display=DisplayPort AUX channel capture}
To see interface DLTs:
dpauxmon --extcap-interface=dpauxmon --extcap-dlts
Output:
dlt {number=275}{name=dpauxmon}{display=DisplayPort AUX channel monitor DLT}
To see interface configuration options:
dpauxmon --extcap-interface=dpauxmon --extcap-config
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
