StarkeBlog - Change MAC Address Permanently

Using ethtool 5.16, and the same USB/Lan Adapter (ASIX AX88179A chipset), and doing ethtool -i enxa0cec88cf7d5 it shows supports-eeprom-access: no

Sure enough, when I try an ethtool -e, it says Cannot get EEPROM data: Operation not supported

Any idea why? Would plugging an eeprom supported device into a Windows computer, and passing it to a Linux VM suddenly make it not writable?

No, it sounds like the NIC chipset does not support writes :-(
