checksum offloading. This feature allows the network stack to delegate
checksum calculation to the network device hardware, improving performance.
Checksum Configuration Options
------------------------------
* :c:macro:`CONFIG_NETDEV_CHECKSUM`: Enable support for hardware checksum
offloading in the network stack. This option requires the architecture
to support it (:c:macro:`ARCH_HAVE_NETDEV_CHECKSUM_HW`).
