Gregory Nutt	c217c663ae	6LoWPAN: Remove the option to disable fragmentation support. Two reasons: (1) First fragementation is always required becaues IPv6 requires an MTU of 1280 bytes. The is no application use case that can work without fragmentation support. And (2) it greatly reduces the complexity of the code.	2017-09-10 10:49:27 -06:00

Gregory Nutt	88a87f8e3f	6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started.	2017-08-26 10:00:47 -06:00
