The creator of that thread liked to change the MAC address form the hardware/firmware given to a different one. Which was fixed during the thread. In this case, the hardware/firmware given MAC changes without user interaction but with a (each?) new kernel. As diffusae wrote during the named thread: > The MAC address isn't stored anywhere.

An so the MAC for ue0 should not. Especially it should start with the fixed range. Ralf
