Iwpriv
is the companion tool to
iwconfig(8).
Iwpriv
deals with parameters and setting specific to each driver (as opposed to
iwconfig
which deals with generic ones).
Without any argument,
iwpriv
list the available private commands available on each interface, and
the parameters that they require. Using this information, the user may
apply those interface specific commands on the specified interface.
In theory, the documentation of each device driver should indicate how
to use those interface specific commands and their effect.
PARAMETERS
private-command [private-parameters]
Execute the specified
private-command
on the interface.
The command may optionally take or require arguments, and may display
information. Therefore, the command line parameters may or may not be
needed and should match the command expectations. The list of commands
that
iwpriv
displays (when called without argument) should give you some hints
about those parameters.
However you should refer to the device driver documentation for
information on how to properly use the command and the effect.
private-command [I] [ private-parameters ]
Idem, except that
I
(an integer) is passed to the command as a
Token Index.
Only some command will use the Token Index (most will ignore it), and
the driver documentation should tell you when it's needed.
-a/--all
Execute and display all the private commands that don't take any
arguments (i.e. read only).
roam
Enable or disable roaming, if supported. Call the private command
setroam.
Found in the
wavelan_cs
driver.
port
Read or configure the port type. Call the private commands
gport_type, sport_type, get_port or set_port
found in the
wavelan2_cs and wvlan_cs drivers.
DISPLAY
For each device which support private commands,
iwpriv
will display the list of private commands available.
This include the name of the private command, the number or arguments
that may be set and their type, and the number or arguments that may
be display and their type.
For example, you may have the following display :
eth0 Available private ioctl : setqualthr (89F0) : set 1 byte & get 0 gethisto (89F7) : set 0 & get 16 int
This indicate that you may set the quality threshold and display an
histogram of up to 16 values with the following commands :
iwpriv eth0 setqualthr 20 iwpriv eth0 gethisto
