IP packet passing through 6lowpan compression and 802.15.4 fragmentation has an issue. (RFC 6282 and 4944) RFC4944, 5.3 says "fragment header's datagram_size and datagram_offset values as the size and offset of the IPv6 datagram before compression". At the moment datagram size and offset values are after compression. Due to multiple bearer (15.4 and bluetooth) support and multiple incoming buffers support functionality is divided to compression and fragmentation parts. And datagram size and offset values for BT are after compression. Small packet (which doesn't need fragmentation) doesn't go through this. So cacheing compressed and uncompressed header lengths and with hdr difference preparing fragments as per original buffer (total buf size and offset).
