I think if the transceiver chip doesn't support such function it could be that some board designer for the transceiver place some eeprom on it. What I mean is somebody builds a CC2520 transceiver board with an eeprom. The eeprom contains the EUI-64 address. Then we need some mechanism to connect them (I think the common way is devicetree) to readout the eeprom and set the perm address. I think this should not touch the driver layer, so random extended addr should be fine. The same is for an eeprom which is placed on the dev board and contains the necessary EUI-64 address information. This is for some further 802.15.4 work. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
