Network
-------
The Cadence network interface driver of LibBSD works on the Xilinx Zynq
platform. The hardware checksum support works on real hardware but does not
seem to be supported on Qemu therefore the default state is to disable
``IFCAP_TXCSUM`` and ``IFCAP_RXCSUM`` and this can be enabled from the shell
with:
.. code-block:: none
ifconfig cgem0 rxcsum txcsum
or with an ``ioctl()`` call to the network interface driver with ``SIOCSIFCAP``
and the mask ``IFCAP_TXCSUM`` and ``IFCAP_RXCSUM`` set.
