+EXTRA_LINUX_MODULES+=('CONFIG_R8169')
+# Q: What requires this option to be enabled?
+# A: Enabling this option adds support for the Realtek RTL8125 2.5GbE Controller
+#    that is present on the Radxa Rock 5 Model B SBC, connected via the PCIe bus.
+#    ```sh
+#    $ sudo lspci -k
+#    0004:01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
+#            Subsystem: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller
+#            Kernel driver in use: r8169
+#            Kernel modules: r8169
+#    ```
+#
+# Q: Why wasn't this option enabled by `make defconfig`?
+# A: There are two reasons for this:
+#    1. None of the symbols that are enabled by the defconfig (built-in or
+#       otherwise)--that are needed by CONFIG_R8169--"select" this option. The
+#       dependencies are already enabled (built-in or otherwise). So all that
+#       needs to be done is to enable this tristate module as a **loadable module**.
+#    2. Since this Ethernet controller is connected via the PCIe bus and is not
+#       the Ethernet PHY offered by the RK3588 SoC itself, it is not selected
+#       by 'CONFIG_ARCH_ROCKCHIP' either.
