According to the RFC4944 (Transmission of IPv6 Packets over IEEE 802.15.4 Networks), chapter 7: The IPv6 link-local address [RFC4291] for an IEEE 802.15.4 interface is formed by appending the Interface Identifier, as defined above, to the prefix FE80::/64. 10 bits 54 bits 64 bits +----------+-----------------------+----------------------------+ |1111111010| (zeros) | Interface Identifier | +----------+-----------------------+----------------------------+ This patch adds IPv6 address generation support for the 6lowpan interfaces.
