There is no need to reserve any space for each frag, as the l2 will
allocate a frag for the ethernet header, arp will do the same.
This is one step further to removing the concept of ll reserve.

Update such statistic on all drivers.
Also, remove TX stats in native and stellaris drivers: such update is
done in L2 now.

It's now either L2 which unref the pkt on successful tx, or net_if on
error.
Also removing pkt->frags check, net_core.c:net_send_data() does it
already.
And using data_len in logging instead of net_pkt_get_len(), which one is
currently greedy (it goes over all net_bufs).

L2 is the one who requests the packet to be sent, and not via net_if API
anymore. Stellaris driver was merged right after this behaviour change
and was thus lacking the proper modification.

The driver can be tested using different networking emulation
approaches.
This approach will work across multiple Qemu instances. There can be
more than one Qemu instance, run using the following command. They
would appear to be on the same Ethernet network.
$ qemu-system-arm -M lm3s6965evb \
-serial stdio \
-net nic \
-net socket,mcast=230.0.0.1:1234 \
-kernel zephyr.elf
This approach will work with other virtualization technologies that
support connecting to a VDE switch, like VirtualBox and User Mode
Linux. The switch can be started using the following command.
$ vde_switch --sock /tmp/switch
Qemu can be connected to the switch using the following command.
$ qemu-system-arm -M lm3s6965evb \
-serial stdio \
-net nic \
-net vde,sock=/tmp/switch \
-kernel zephyr.elf
