Which led to write junk as an address into cc2520 and thus made the
chip filtering out all unicast packet (as the incoming address never

Helper functions to read and write data across multiple fragments.
Write function always adds at the end of last fragment. If there is
no space in last fragment new data fragment will be created and added
to input buffer.
Read function start reading from offset of input fragment. If the
required data is located in mutliple fragments it reads from list
of fragments and returns position and fragment where read stopped.
Skip function start skipping from offset of input fragment. If the
required length is across multiple fragments it skip till length and
returns position and fragment where read stopped. This is useful
when reading with unwanted data (reserved or unhandled data).
These functions are quite useful when handling with multiple fragments.

In case of broadcast or multicast destination address, ARP
message is not required. But ethernet_send assumes net_arp_prepare()
returns ARP buffer and doesn't fill any LL header information in
all fragments.
So checking whether destination address is broadcast or multicast
in ethernet and fill LL headers according to the case. Lets assume
if net_arp_prepare() returns success means that is ARP message.

If the connection establishment has an error, the accept
callback needs to be able to return that error to user space
so that the application can know about it.
This is especially important in TCP where application needs
to start to listen again if reset is sent during connection
establishment.
