I find you make it difficult to read without need by explaining it
backwards.

	The environment variable will be compared to the driver
	initialized struct eth_device->enetaddr. If they differ, a
	warning is printed, an the environment variable will be used
	unchanged.

	If the environment variable is not set, it will be initialized
	from eth_device->enetaddr, and a warning will be printed.

Best regards,

Wolfgang Denk
