NAME

       iwpriv - configure optionals (private) parameters of a wireless network interface

SYNOPSIS

       iwpriv [interface]
       iwpriv interface private-command [private-parameters]
       iwpriv interface private-command [I] [private-parameters]
       iwpriv interface --all

DESCRIPTION

       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).

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
