  12. KernelVersion: 2.6.27
  13. Description:
  14. If no beacons are received from a device for at least
  15. this time, the device will be considered to have gone
  16. and it will be removed. The default is 3 superframes
  17. (~197 ms) as required by the specification.

  28. Description:
  29. Write:
  30. <channel>
  31. to force a specific channel to be used when beaconing,
  32. or, if <channel> is -1, to prohibit beaconing. If
  33. <channel> is 0, then the default channel selection
  34. algorithm will be used. Valid channels depends on the
  35. radio controller's supported band groups.
  36. Reading returns the currently active channel, or -1 if
  37. the radio controller is not beaconing.

  42. Description:
  43. The application-specific information element (ASIE)
  44. included in this device's beacon, in space separated
  45. hex octets.

  69. radio controller. A write will change the radio
  70. controller's EUI-48 but only do so while the device is
  71. not beaconing or scanning.
