"iwpriv" command line interface to driver parameters

• Madwifi provides an ioctl based command line interface "iwpriv" to set certain driver parameters specific to the wireless interface.
  

Usage of iwpriv

• Typing iwpriv on the command line would give a list of the available private ioctls for each of the wireless interfaces that are up.
  

For example,

node1-1:~# iwpriv
eth0 no private ioctls.

eth1 no private ioctls.

lo no private ioctls.

ath0 Available private ioctls :

• To set a parameter using an available ioctl, one can issue a following command

iwpriv <interface name> <an iotcl name with set flag 1> value.
For example, to set the periodic noise floor calibration interval to a value of 3 seconds on interface ath0, issue the following command.

iwpriv ath0 calint 3

• To get a parameter using an available ioctl, one can use the following command

iwpriv <interface name> <an ioctl name with get flag 1> value.
For example, to get the periodic noise floor calibration interval,

iwpriv ath0 get_calint
