This is a simple test of the netwok loopback device. examples/nettest can also be configured to provide (better) test of local loopback transfers. This version derives from examples/poll and is focused on testing poll() with loopback devices.

Dependencies:

• CONFIG_NET_LOOPBACK – Requires local loopback support.

• • CONFIG_NET_TCP – Requires TCP support with the following:

    • CONFIG_NET_TCPBACKLOG
    • CONFIG_NET_TCP_WRITE_BUFFERS

• CONFIG_NET_IPv4 – Currently supports only IPv4.
