Title: Blip stack modifications according to RFC 6282

According to RFC 6282 Header compression for 6LoWPAN ,generating IP Address from short address is of the form fe80:0000:0000:0000:0000:00ff:fe00:XXXX,where XXXX is the 16-bit short Address of the node.Whereas the current blip stack is generating IP Address in the form : fe80:0000:0000:0000:panid:00ff:fe00:XXXX,

Also one more modification in the blip stack is the fragmentation of multicast packets.In the fragmentation process,it divides whole packet into fragments,and will send first fragment and only after receiving the acknowledgement of the first fragment it will send the next fragment. Coming to our issue is that for multicast packets ,which will be broadcasted on layer2 , and are not acknowledged back... So, blip stack will never send the second fragment of the multicast packet as it will be waiting for the acknowledgement of the first fragment which will never come
