The permanent mac address should be available for query when the device

NetworkManager, the system network daemon, uses 'ethtool -P' to obtain
the permanent address after the kernel start. When the network device
is not up, it will return the device busy error with 'ethtool -P'. At
that time, it is unable to access the Internet through the permanent
address by NetworkManager.
I think that the '.begin' is not used to check if the device is up.

You forgot to update the commit message.
