In-between the MAC & PHY there can be a mode converter, which converts one mode to another (e.g. GMII-to-RGMII). The converter, can be passive (i.e. no driver or OS/SW information required), so the MAC & PHY need to be configured differently. For the `stmmac` driver, this is implemented via a `mac-mode` property in the device-tree, which configures the MAC into a certain mode, and for the PHY a `phy_interface` field will hold the mode of the PHY. The mode of the PHY will be passed to the PHY and from there-on it work in a different mode. If unspecified, the default `phy-mode` will be used for both.
