the tests are also run.

When running echo-server in the Zephyr device (either a real
device or qemu), set the IPv6 address to be 2001:db8::2.
The host IPv6 address should be set to 2001:db8::1 in this case.

The prj_slip.conf file should be used for qemu-to-host

if we have Qemu-to-Qemu communication, clearly tell this

Packet is compressed after its ll part has been computed when sending.
And it is then decompressed after the ll part has been validated when
receiving.

Reassembly IEEE 802.15.4 fragments as per it's datagram size
and datagram tag. Uncompress IP header fragment as soon as it
arrives. Size matches only after uncompression of IP header with
total length.
Support added for multiple IP packet reception. Default is one full
IP packet at a time. Cache size can be modified via Kconfig option
(NET_L2_IEEE802154_FRAGMENT_REASS_CACHE_SIZE).
Note: If you increase the size by 1 means, you should have N number
of data buffers available at max.
e.g. One full IP packet (1280 MTU) needs 15~16 data fragments means,
multiply size by same number of fragments. It requires more memory.
Offset based reassembly yet to be done (fragments can come in any order
[e.g. mesh]). Now assuming that fragments are in right order.
