       iwevent - Display Wireless Events generated by drivers and setting changes


       iwevent	display  Wireless Events received through the RTNetlink socket. Each line display
       the specific Wireless Event which describe what has happened  on  the  specified  wireless
       This command doesn't take any arguments.

       There is two classes of Wireless Events.

       The first class is events related to a change of wireless settings on the interface (typi-
       cally done through iwconfig or a script	calling  iwconfig).   Only  settings  that  could
       result  in  a  disruption  of connectivity are reported. The events currently reported are
       changing one of the following setting :
	    Network ID
       All those events will be generated on all wireless interfaces by the kernel wireless  sub-
       system (but only if the driver has been converted to the new driver API).

       The second class of events are events generated by the hardware, when something happens or
       a task has been finished. Those events include :

       New Access Point/Cell address
	      The interface has joined a new Access Point or Ad-Hoc Cell, or lost its association
	      with it. This is the same MAC address that is reported by iwconfig.

       Scan request completed
	      A  scanning  request  has  been  completed,  results of the scan are available (see

       Tx packet dropped
	      A packet directed at this address has been dropped because the  interface  believes
	      this  node  doesn't answer anymore. An early indication that the node may have left
	      the cell or gone out of range.

       Custom driver event
	      Event specific to the driver. Please check the driver documentation.

       Registered node
	      The interface has successfully registered a new wireless client/peer. Will be  gen-
	      erated mostly when the interface act as an Access Point (mode master).

       Expired node
	      The  registration  of the client/peer on this interface has expired. Will be gener-
	      ated mostly when the interface act as an Access Point (mode master).

       Only some of those events will be generated on some wireless interfaces	by  the  wireless
       driver, and their support depend on the specific hardware/driver combination. Please refer
       to driver documentation for details.
