+Subject: [PATCH 1/7] net: ethernet: mtk_eth_soc: add MTK_NETSYS_V1 capability
+ bit
+
+Introduce MTK_NETSYS_V1 bit in the device capabilities for
+MT7621/MT7622/MT7623/MT7628/MT7629 SoCs.
+Use !MTK_NETSYS_V1 instead of MTK_NETSYS_V2 in the driver codebase.
+This is a preliminary patch to introduce support for MT7988 SoC.

+From: Daniel Golle <daniel at makrotopia.org>
+Date: Wed, 1 Mar 2023 11:56:04 +0000
+Subject: [PATCH 7/7] net: ethernet: mtk_eth_soc: add paths and SerDes modes
+ for MT7988
+
+MT7988 comes with a built-in 2.5G PHY as well as USXGMII or 10Base-KR
+compatible SerDes lanes for external PHYs.
+Add support for configuring the MAC and SerDes parts for the new paths.
