Subject: [PATCH 3/3] net: phy: mediatek-ge: do not disable EEE advertisement
Date: Mon, 18 Mar 2024 10:46:25 +0300	[thread overview]
Message-ID: <20240318-for-net-mt7530-fix-eee-for-mt7531-mt7988-v1-3-3f17226344e8@arinc9.com> (raw)
In-Reply-To: <20240318-for-net-mt7530-fix-eee-for-mt7531-mt7988-v1-0-3f17226344e8@arinc9.com>

There's no need to disable Energy-Efficient Ethernet (EEE) advertisement on
the MT7530 and MT7531 switch PHYs. EEE works fine on MT7530 and MT7531
switch PHYs. Remove the code where EEE advertisement is disabled.

This is a bugfix because there's a possible race condition where the
mediatek-ge driver would kick in after the MT7530 DSA subdriver which would
have EEE disabled until manually enabled.

Fixes: e40d2cca0189 ("net: phy: add MediaTek Gigabit Ethernet PHY driver")
