It seems rather interesting that WoL is disabled in the config_init()
method - because this will be called when the PHY is attached to its
network driver (reasonable I guess) but also at resume time - which
means one can't just set the WoL mode once and that status will be
preserved.

Maybe Andrew can clarify, but I thought once WoL was configured, that
configuration should remain until the system is rebooted.
