Signed-off-by: Love Kumar love.kumar@amd.com --- Changes in v2: - Mark CMD_MII command dependency
Changes in v3: - Skip the test if PHY device not present
Changes in v4: - Setup the network configuration by running dhcp test at the end of test - Add option to skip the test if it is not desired or possible --- test/py/tests/test_net.py | 57 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+)
