From: Klaus Goger klaus.goger@theobroma-systems.com

Generate a MAC address based on the cpuid available in the efuse block: Use the first 6 byte of the cpuid's SHA256 hash and set the locally administered bits. Also ensure that the multicast bit is cleared.

The MAC address is only generated and set if there is no ethaddr present in the saved environment.
