The FEC does not have a PHY so it should not have a phy-handle. It is connected to the switch at RGMII level so we need a fixed-link sub-node on both ends.
This was not a problem until the qca8k.c driver was converted to PHYLINK by commit b3591c2a3661 ("net: dsa: qca8k: Switch to PHYLINK instead of PHYLIB"). That commit revealed the FEC configuration was not correct.
