While the current approach for garbage collection in the 6Lo reassembly buffer is good for best-effort handling of *fragmented* packets and nicely RAM saving, it has the problem that incomplete, huge datagrams can basically DoS a node, if no further fragmented datagram is received for a while (since the packet buffer is full and GC is not triggered). This change adds a asynchronous GC (utilizing the existing functionality) to the reassembly buffer, so that even if there is no new fragmented packet received, fragments older than `RBUF_TIMEOUT` will be removed from the reassembly buffer, freeing up the otherwise wasted packet buffer space. |
