The return value for eth_getenv_enetaddr_by_index produces a Warning when ethXaddr is not set (env_enetaddr is equal to 00:00:00:00:00:00).
The validity of the mac address is tested later in this function to avoid to write an erroneous address.
The test of the function's return is consequently useless and adds a warning.
