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


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


       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.


       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.

              Execute and display all the private commands that don’t take any
              arguments (i.e.  read only).


       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
