Using macros does not let the compiler verifying about the type we are
providing, which usually give an error easier to understand.
Also, this will let the compiler deciding how to actually optimize
(inline or not) the code.

If the MTU is bigger than fragment size, we must leave the
fragment link layer header empty so that the received data
count does not get wrong.

There is no harm for doing so but debug prints will look
weird in this case.

There will be a crash if network device sends data to network
stack before it is ready to receive such data.

The code was using NET_DBG() which is not really available
for the slip/tap driver.

As there is a L2 in the middle, there is no need for
net_if to provide such information.

Net core then does not know anything about l2 related logic.
For instance ARP is used in ethernet l2 API and nowhere else.
This will be helpful when adding different technologies altogether.
Currently, only SLIP driver is enabled to use relevant l2 layer.

added before the packet.

Renamed net_recv() to net_recv_data() so that the more generic
name can be used by applications. The net_recv_data() is only
meant to be used when L2 layer feeds data into L3 (IP) layer.

The SLIP driver is using UART pipe driver to communicate with
host when Zephyr is running in Qemu. Currently this is only
used by networking sub-system when testing the networking
stack.
