Add below test cases for mii commands: mii_info -To display MII PHY info mii_list - To list MII devices mii_set_device - To set MII device mii_read - To reads register from MII PHY address mii_dump - To display data from MII PHY address
Signed-off-by: Love Kumar love.kumar@amd.com --- Changes in v2: - Get MII device list from env instead of auto-detecting it - Set the MII device to its current device after testing so that it won't impact next cases --- test/py/tests/test_mii.py | 92 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 92 insertions(+) create mode 100644 test/py/tests/test_mii.py
