# IMPORTANT: Set CN0506 interface mode
#
# The get_env_param procedure retrieves parameter value from the environment if exists,
# other case returns the default value specified in its second parameter field.
#
#   How to use over-writable parameters from the environment:
#
#    e.g.
#      make INTF_CFG=MII
#
#    INTF_CFG  - Defines the interface type (MII, RGMII or RMII)
#
# LEGEND: MII
#         RGMII
#         RMII
