Daniel Golle March 7, 2023, 3:55 p.m. UTC 
From: Lorenzo Bianconi <lorenzo@kernel.org>

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.
