Printing the file descriptor does not give any information when
the network interface creation fails, so print errno here instead.

Rather than having each driver have its own slightly different way of
generating a random mac address, add a helper function that they all can

By changing the various *NET_DEVICE* macros. It is up to the device
drivers to either set a proper PM function or, if not supported or PM
disabled, to use device_pm_control_nop relevantly.
All existing macro calls are updated. Since no PM support was added so
far, device_pm_control_nop is used as the default everywhere.

The current design of the network-specific stack dumping APIs
is fundamentally unsafe. You cannot properly dump stack data
without information which is only available in the thread object.
In addition, this infrastructure is unnecessary. There is already
a core shell command which dumps stack information for all
active threads.

If the Ethernet driver has VLAN enabled (only native_posix, mcux
or gmac has VLAN supported), then the iface pointer in ethernet
context should contain the main network interface. This is needed
so that the interface will get link address set to it properly.

TCP segment with several EOL TCP options causes echo server to block and

Don't sleep 50ms after each received packet, sleep only when there
wasn't anything to receive. Otherwise data could get stuck for a long
time if there was more than 20 packets coming in per second. The
read() call on a TUN/TAP device returns only a single packet per call.
Also remove the call to eth_stats_update_errors_rx() because this else
clause isn't actually a receive error, we're just waiting for more
packets.

Use the new API where relevant. Only sam_gmac is left aside for now.
This simplifies a lot the code as the caller should only care about
allocating net_pkt and its buffer once, and thus will not need to mess
with "frags" etc...

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.

Now instead of such path:
net_if_send_data -> L2's send -> net_if tx_queue -> net_if_tx -> driver
net_if's send
It will be:
net_if_send_data -> net_if tx_queue -> net_if_tx -> L2's send -> driver
net_if's send

Change the default behaviour of the host network interface
setup. Now user needs to execute net-setup.sh script from
net-tools project to setup host ethernet interface. The script
needs to be run as a root user. Then zephyr.exe can be started
as a normal user.
Example:
cd net-tools
sudo ./net-setup.sh
This will create zeth network interface and set IP address and
routes properly. See other command line options by typing
./net-setup.sh --help
Old behaviour is still there if one enables
CONFIG_ETH_NATIVE_POSIX_STARTUP_AUTOMATIC=y
in which case one needs to use the command
sudo --preserve-env zephyr.exe
to start the Zephyr process.

User can take the zeth interface down by issuing "net iface down <idx>"
shell command. It is possible to take the interface up by typing
"net iface up <idx>" in shell. These commands are important for
native_posix as there is no physical cable that can be connected
or disconnected.

The advantage to this approach allows drivers for
devices that already keep statistics data on hardware
registers to use those instead, rather than try to
replicate it the same counters again within the driver
itself.
The eth_native_posix.c driver though do not benefit
from this, is modified to use the new callback system.

Create infrastructure that allows ethernet device driver to tell
if it supports network packet checksum offloading. This applies only
to IPv4, UDP or TCP checksums. The driver can enable/disable checksum
offloading separately for Tx and Rx network packets.
If the device (ethernet in this case) can calculate the network
packet checksum for IPv4, UDP or TCP, then do not calculate the
corresponding checksum by the stack itself.
