Variable len is related uIP stack. datalen is actual variable which
needs to be set zero in net_buf_get_reserve.

Have a separate network buffer pool for received and transmitted
data. This way incoming packet flood cannot prevent from sending
IP packets out.

6lowpan HC06 and HC01 compression/uncompression functions are
adapted to net_mbuf buffers. HC06 compression and uncompression
works properly. HC01 adapted to net_mbuf but functionality is
failing due to inproper IPv6 link local addresses. buf pointers
from net_mbuf and couple of net_mbuf calls are removed (which
are not used at the moment and saves memory from net_mbuf).

Enable 802.15.4 driver that receives the IPv6 packet, does header
compression on it and writes it to the 15.4 stack Tx FIFO.
The 15.4 Tx fiber will pick up the header compressed IPv6
6LoWPAN packet and fragment it into suitable chunks ready
to be sent to the 15.4 hw driver. The 15.4 stack Rx fiber picks
15.4 frames from 15.4 Rx FIFO (which are fed by 15.4 driver)
and reassembles the all fragmented packets and uncompress the
header and writes to the IP Rx FIFO.
The 15.4 loopback radio driver receives the 15.4 frames and
put it back to 15.4 Rx Fifo.

We do not need large 1280 bytes long buffers in lower IP stack
layers. After long packet has been fragmented to smaller chunks
it depends on the radio technology how long buffers we need
to use. For 802.15.4 we can use 128 bytes long buffers.
