For the "everything old is new again" files, back in the 1990s, it was
noticed that on the likes of a netperf UDP_STREAM test on HP-UX, with
fragmentation taking place, it was possible to consume 100% of the link
bandwidth and have 0% effective throughput because the transmit queue
was kept

Hi,
On linux-wpan we had a discussion about setting the right tx_queue_len
and came to some issues in 802.15.4 6LoWPAN networks.
Our hardware parameters are:
- Bandwidth: 250kb/s
- One framebuffer at hardware side for transmit a frame.
- MTU - 127 bytes (without mac headers)
