it to a proper one.

If a data packet is received with AR flag set, it will reply
accordingly. This is meaningful when running the stack above hardware
that cannot reply automatically to ACK request.

This is the simplest - if not the dumbest - radio protocol we can use
for IEEE 802.15.4 stack. It just transmsits right away (with optional
retry) without taking care of doing any CCA (Clear Channel Assesment).
See IEEE 802.15.4 specification document, part 4.5.4.2

The dst_ip6 is a parameter, required for future 802.15.4 L2 layer.
At some point such parameter could be changed to a void pointer,
and a utility function would populate it depending on L2 layer,
if such parameter needs someday to be variable and complex (some
specific struct or else).
Also make sure we use ARG_UNUSED() relevantly, and using proper prefix
to functions.

The options length check was using fragment length to
verify the correctness of options. This is incorrect
as we need to check against the remaining length of the
