30 is used to set a list of addresses in a wireless network interface and
31 to read back quality of link information for each of those. This
32 information is the same as the one available in
34 : quality of the link, signal strength and noise level.
36 This information is updated each time a new packet is received, so
37 each address of the list add some overhead in the driver.
40 Can also display the list of frequencies available for the device or the
41 list of Access Points in range.
46 You may set any number of addresses up to 8.
49 Set an IP address, or in some cases a domain name. As the hardware
50 work with hardware addresses,
52 will translate this address through
54 In some case, this address might not be in the ARP cache and
56 will fail. In those case,
58 this address and retry.
61 Set a hardware (MAC) address (this address is not translated & checked
62 like the IP one). The address must contain a semicolon
64 to be recognised as a hardware address.
67 Add the new set of addresses at the end of the current list instead of
68 replacing it. The address list is unique for each device, so each user
69 should use this option to avoid conflicts.
72 Remove the current list of addresses and disable the spy functionality
75 Give the list of available frequencies in the device and the number of
76 defined channels. Please note that usually the driver returns the
77 total number of channels and only the frequencies available in the
78 present locale, so there is no one to one mapping between frequencies
79 displayed and channel numbers.
82 Give the list of Access Points in range, and optionally the quality of
85 .BR rate / bit [ rate ]
86 List the bit-rates supported by the device.
