ieee802154, mac802154: implement devkey record option
The 802.15.4-2011 standard states that for each key, a list of devices that use this key shall be kept. Previous patches have only considered two options: * a device "uses" (or may use) all keys, rendering the list useless * a device is restricted to a certain set of keys Another option would be that a device *may* use all keys, but need not do so, and we are interested in the actual set of keys the device uses. Recording keys used by any given device may have a noticable performance impact and might not be needed as often. The common case, in which a device will not switch keys too often, should still perform well. Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.
