Subject: [PATCH net-next 13/14] net: ethernet: mtk_eth_soc: introduce MTK_NETSYS_V2 support

Introduce MTK_NETSYS_V2 support. MTK_NETSYS_V2 defines 32B TX/RX DMA
descriptors.
This is a preliminary patch to add mt7986 ethernet support.

Tested-by: Sam Shih <sam.shih@...iatek.com>
Signed-off-by: Lorenzo Bianconi <lorenzo@...nel.org>
