Avoid copying (cloning) the data to be transmitted and
just increase the reference count of the original buffer.
This is more efficient and reduces memory and CPU usage.

By default the DWMAC ethernet controller is configured
to drop all multicast packets. Currently, HW filtering is
not supported, so we need to configure the controller to
pass all multicast packets.

As net_if_set_link_addr() is now already done by the
overlaying net_mgmt, we no longer need to do it
in the drivers

Add support for configuring the MAC based on the PHY link state.
This allows the driver to properly set the speed and duplex
settings of the MAC when the link state changes.

Add a Kconfig option to configure the RX refill thread priority.
The default is set to 0, which is the same as the previous hardcoded
value. This allows users to set a different priority if needed.

Thread priority was passed to options argument of k_thread_create,
instead of the priority argument.

Fix warnings about using char * for %p argument in cbprintf. It's
recommended to cast it to void * because it may cause misbehavior
in certain configurations.

Change return value of dwmac_platform_init to int and return error code
in case of failure. This allows to report errors from platform init and
fail the driver probe if platform init fails.

net_pkt_get_frag() and a few other functions did not specify the
allocated fragment length, incorrectly assuming that fixed-sized
buffers are always used.
In order to make the function work properly also with variable-sized
buffers, extend the function argument list with minimum expected
fragment length parameter. This allows to use net_buf_alloc_len()
allocator in variable buffer length configuration, as well as verify if
the fixed-sized buffer is large enough to satisfy the requirements
otherwise.
Update the existing codebase to provide the expected fragment length,
based on the context.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

This is a driver for the Synopsys DesignWare MAC. It should work
with the "DesignWare Cores Ethernet Quality-of-Service" versions 4.x
and 5.x.
This driver uses a zero-copy strategy, meaning that the hardware
reads and writes data directly from/to packet fragment buffers
provided by the network subsystem without first copying the data into
a dedicated DMA bounce buffer.
Platform specific setup is necessary for the hardware to work.
Currently, only the STM32H7X series is implemented and tested.
While this part needs refinement, this driver performs better and uses
far less code space than the HAL-based alternative.
Not yet implemented:
- MDIO (it is WIP, currently relying on default PHY config)
- PTP support
- VLAN support
- various hardware offloads (when available)
