- Arm FVP BaseR AEMv8-R
- ARM BASE RevC AEMv8A Fixed Virtual Platforms

For best performance, the sample configures a lot of network packets and buffers.
Because of this, the sample's RAM requirements are quite large. In case the
sample does not fit into target platform RAM, reduce the following configs:

.. code-block:: cfg

CONFIG_NET_PKT_RX_COUNT=40
CONFIG_NET_PKT_TX_COUNT=40
CONFIG_NET_BUF_RX_COUNT=160
CONFIG_NET_BUF_TX_COUNT=160
