This isn't a criticism for this patch, but a discussion point for
phylib itself.

It occurs to me that there's a weakness in the phylib interface for WoL,
specifically when WoL is enabled at the PHY, but someone then changes
the interface's MAC address - there doesn't seem to be a way for the
address programmed into the PHY to be updated. Should there be?

Do we instead expect users to disable WoL before changing the MAC for
a network interface?
