* Update the linux-zigbee git:// repository URL. * The IEEE 802.15.4 MLME based netlink operations are documented in include/linux/nl802154.h, not in include/net/nl802154.h. * The hardmac example driver 'fakehard' was removed some time ago. * The IEEE 802.15.4 device drivers live in drivers/net/ieee802154/, not in drivers/ieee802154/. * The IEEE 802.15.4 MTU is 127 bytes, not 128 bytes. * Some of the 6LoWPAN code lives in net/6lowpan/.
