Well, if ther eis no MAC address in the fuse, and there is no
"ethaddr" setting in the current environment, then nothing should
happen until you try to run the first network command, at wich point
the command should fail because the MAC address is unset.

This is broken behaviour; in this case, the network driver needs to be
fixed. The driver initialization takes place when you start a network
command, and it should pick up the MAC address setting then, mo matter
if this was permanently stored or just entered on the command line.

Best regards,
