+Expected result
+===============
+The test will initialize all basic networking functionality including the
+minimal NRF51822 radio driver and run the shell providing netif shell commands.
+
+Background
+==========
+Use the shell commands to test the link layer functionality of the minimal
+NRF51822 radio driver (nrfmin).
