Subject: [PATCH 5.10 72/74] net: dsa: mt7530: make NET_DSA_MT7530 select MEDIATEK_GE_PHY

From: Arınç ÜNAL <arinc.unal@...nc9.com>

commit 4223f86512877b04c932e7203648b37eec931731 upstream.

Make MediaTek MT753x DSA driver enable MediaTek Gigabit PHYs driver to
properly control MT7530 and MT7531 switch PHYs.

A noticeable change is that the behaviour of switchport interfaces going
up-down-up-down is no longer there.
