Jukka Rissanen e6d1925a96 net: Make sure Contiki will not remove received packet We must not touch uip_len(buf) value as Contiki IP stack will use it to determine what it should do with the received packet. So after we have received the packet, we update separate datalen variable in net_buf that will store the correct length of the packet.

802.15.4 test Application:

 1) Loopback in single qemu:
 Enable CONFIG_NETWORKING_WITH_15_4_LOOPBACK config option in prj_x86/arm.conf
 to test 802.15.4. By enabling this option dummy driver will feed sending
 802.15.4 frames back to 15_4 Rx FIFO. 15_4 Rx FIFO will asseble all frames
 and feed it to IP Rx FIFO.

 2) Loopback between two qemus:
 Enable CONFIG_NETWORKING_WITH_15_4_LOOPBACK_UART config option in
 prj_x86/arm.conf to send 802.15.4 frames out through QEMU UART and receive
 frames through QEMU UART.

 Follow below simple steps to create fifos at host.

 $ mkfifo /tmp/ip-15-4-1.{in,out}
 $ ln /tmp/ip-15-4-1.in /tmp/ip-15-4-2.out
 $ ln /tmp/ip-15-4-1.out /tmp/ip-15-4-2.in

 Open two terminals and run two qemus with below options.
 $ make qemu QEMU_NUM=1 CONFIG_NETWORKING_WITH_15_4_LOOPBACK_UART=y
 $ make qemu QEMU_NUM=2 CONFIG_NETWORKING_WITH_15_4_LOOPBACK_UART=y
