Hi Vladimir > + /* Internal port with DSA tagging */ > + mscc_felix_port4: port@4 { > + reg = <4>; > + phy-mode = "gmii"; Is it really using gmii? Often in SoC connections use something else, and phy-mode = "internal" is more appropriate. > + ethernet = <&enetc_port2>; > + > + fixed-link { > + speed = <2500>; > + full-duplex; > + }; gmii and 2500 also don't really go together.
