*Synopsys DesignWare MAC driver*

Type: ``bool``

Help
====

.. code-block:: none

    This is a driver for the Synopsys DesignWare MAC, also referred to
    as "DesignWare Cores Ethernet Quality-of-Service". Hardware versions
    4.x and 5.x are supported.

    Platform specific glue support is also required. This driver is
    currently available on targets using the STM32H7X series as an
    alternative to the eth_stm32_hal driver. Support for a generic DT
    and MMU based platform is also provided.

    Not yet implemented:
    - MDIO (currently relying on default PHY config)
    - PTP support
    - VLAN support
    - various hardware offloads (when available)
