Sadly, I have not received the datasheet. All comes from studying different versions of the driver.

On the BananiPi-R3 Mini the RX pair is reversed:

	phy14: ethernet-phy@14 {
		reg = <14>;
		interrupts-extended = <&pio 48 IRQ_TYPE_EDGE_FALLING>;
		reset-gpios = <&pio 49 GPIO_ACTIVE_LOW>;
		reset-assert-us = <10000>;
		reset-deassert-us = <20000>;
		phy-mode = "2500base-x";
		full-duplex;
		pause;
		airoha,rx-pol-reverse;

		leds {
			#address-cells = <1>;
			#size-cells = <0>;

			led@0 { /* en8811_a_gpio5 */
				reg = <0>;
				color = <LED_COLOR_ID_YELLOW>;
				function = LED_FUNCTION_LAN;
				function-enumerator = <1>;
				default-state = "keep";
				linux,default-trigger = "netdev";
			};
			led@1 { /* en8811_a_gpio4 */
				reg = <1>;
				color = <LED_COLOR_ID_GREEN>;
				function = LED_FUNCTION_LAN;
				function-enumerator = <2>;
				default-state = "keep";
				linux,default-trigger = "netdev";
			};
		};
	};
