[PATCH net-next v4 02/10] net: stmmac: Add support for Allwinner A523 GMAC200

[Russell King (Oracle)]

Hi,

I drafted this but never sent it and can't remember why, but it's
relevant for v5 that you recently posted. Same concern with v5.

I'm guessing that there's no way that plat->phy_interface !=
plat->mac_interface on this platform? If so, please use
