The ethernet driver calls net_set_mac before net_init is
called (ie before the uip stack has been fully initialized).
Unfortunately net_set_mac calls the function uip_ds6_set_lladdr.
Therefore this function is called before uip_ds6_init: this is an
issue as uip_ds6_set_lladdr is setting some static data which are
going to be erased by uip_ds6_init. In some case it could even lead
to a system hang due to a timer set twice.
To fix this issue net_set_mac should check whether net_init has been
already called. If not net_set_mac should simply copies the mac
address into uip_lladdr. Indeed uip_ds6_init automatically calls
uip_ds6_set_lladdr for the address stored into uip_lladdr.

The line below is wrong and useless:
lladdr->state = ADDR_AUTOCONF;
Indeed the three possible values for the state attribute are:
ADDR_TENTATIVE, ADDR_PREFERRED or ADDR_DEPRECATED. ADDR_AUTOCONF
is one possible value for the type attribute.
Moreover uip_ds6_set_lladdr already set the type attribute to
ADDR_AUTOCONF (this done through the call to the function
uip_ds6_addr_add).
Therefore this issue has been simply fixed by removing the line.

If TinyCrypt ECC is used for LE SC calculations need to be done
in task to avoid hogging CPU from non-preemptible fiber. To keep
upper layers of stack independent of crypto used (TinyCrypt or
controller) this patch adds HCI ECC emulation.
If ECC emulation is enabled it is always used regardless of ECC
support being present in controller.

IP packet passing through 6lowpan compression and 802.15.4
fragmentation has an issue. (RFC 6282 and 4944) RFC4944, 5.3
says "fragment header's datagram_size and datagram_offset
values as the size and offset of the IPv6 datagram before
compression".
At the moment datagram size and offset values are after
compression. Due to multiple bearer (15.4 and bluetooth) support
and multiple incoming buffers support functionality is divided
to compression and fragmentation parts. And datagram size and
offset values for BT are after compression. Small packet (which
doesn't need fragmentation) doesn't go through this. So cacheing
compressed and uncompressed header lengths and with hdr difference
preparing fragments as per original buffer (total buf size and offset).
