This reverts the commit cdf49c283e2e105da86ca575ad35b453f5ff24ea which replaces lowpan '.ndo_set_mac_address' method by ethernet's one. Accorind to the IEEE 802.15.4 standard, device has 8-byte length address, so this hook loses the last 2 bytes which may rise a compatibility problems with other IEEE 802.15.4 standard implementations.
