Dear Krzysztof,
Thanks for your comments.

No need for new entry. > mt8188 and mt8195 are different SoCs and we need to distinguish mt8188 from mt8195, so I think a new entry is needed for mt8188 with the specific "compatiable". On the other hand, mt8188 and mt8195 have same ethernet design, so the private data "mt8195_gmac_variant" can be resued to reduce redundant info in driver.
