       iwspy - Get wireless statistics from specific nodes

       iwspy interface
       iwspy interface [+] DNSNAME | IPADDR | HWADDR [...]
       iwspy interface off

       Iwspy  is used to set a list of addresses in a wireless network interface and to read back
       quality of link information for each of those. This information is the  same  as  the  one
       available in /proc/net/wireless : quality of the link, signal strength and noise level.

       This  information  is  updated  each time a new packet is received, so each address of the
       list add some overhead in the driver.

       Note the this functionality work only for node part of the current wireless cells.

       You may set any number of addresses up to 8.

	      Set an IP address, or in some cases a DNS name (using the name  resolver).  As  the
	      hardware work with hardware addresses, iwspy will translate this IP address through
	      ARP.  In some case, this address might not be in the ARP cache and iwspy will fail.
	      In those case, ping(8) this name/address and retry.

       HWADDR Set  a hardware (MAC) address (this address is not translated & checked like the IP
	      one). The address must contain a colon (:) to be recognised as a hardware address.

       +      Add the new set of addresses at the end of the current list  instead  of	replacing
	      it. The address list is unique for each device, so each user should use this option
	      to avoid conflicts.

       off    Remove the current list of addresses and disable the spy functionality
