I'm doing some research on old kernels and running the following on 2.6.7 or 2.6.8 gives a resource busy error. But on 2.6.28 the command works as expected. How would I determine which kernel allowed this command to change the mac address on the fly? ip link set dev addr

You can see some screenshots below. Thank you! alt text alt text alt text
