The phylink_stop is called before phylink_disconnect_phy
You could see in mvpp2.c:
mvpp2_stop_dev() {
phylink_stop(port->phylink);
}
mvpp2_stop() {
mvpp2_stop_dev(port);
phylink_disconnect_phy(port->phylink);
}
.ndo_stop = mvpp2_stop,

Are you calling phylink_stop() or are you just calling phylink_disconnect() ?
You must call phylink_stop() prior to phylink_disconnect(). This probably explains why the p21 patch did nothing.
