From: Arınç ÜNAL <arinc.unal@arinc9.com> stable inclusion from stable-v5.10.99 commit f1f7d1a22fd73034af73d51086b2fe2981d02028 bugzilla: https://gitee.com/openeuler/kernel/issues/I55O7H Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- 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.
