Subject: [RFC radvd 1/2] device-linux: replace ARPHRD_IEEE802154 to ARPHRD_6LOWPAN

This patch changes the ARPHRD_IEEE802154 to ARPHRD_6LOWPAN. The IEEE
802.15.4 6lowpan module changed the ARPHRD_IEEE802154 type to
ARPHRD_6LOWPAN. Nowadays it's use ARPHRD_6LOWPAN which is also used by
BTLE 6LoWPAN. Both interfaces uses an EUI64 address and the handling to
get the link-layer address should be the same.

There is no backward compatibility for 802.15.4 6LoWPAN before we
changed the ARPHRD. Anyway if somebody wants that it should be patched
manually. When the ARPHRD was ARPHRD_IEEE802154 the 802.15.4 6lowpan was
anyway in a somehow unusable state.
