4 Subject: [PATCH 105/250] net: ethernet: mtk_eth_soc: add basic support for
5 MT7988 SoC
6
7 Introduce support for ethernet chip available in MT7988 SoC to
8 mtk_eth_soc driver. As a first step support only the first GMAC which
9 is hard-wired to the internal DSA switch having 4 built-in gigabit
10 Ethernet PHYs.
