Subject: mediatek: build driver for built-in 2.5GE PHY as module
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bf0825a2d036295eec0cef3e8807e80a08460b63;p=thirdparty%2Fopenwrt.git

mediatek: build driver for built-in 2.5GE PHY as module

The by-now-upstream driver for the built-in 2.5GE PHY of the MediaTek
MT7988 and MT7987 SoC loads firmware at probe time.

Build the driver as a module in order to make sure the driver only
attempts to load the firmware by the time the rootfs with the firmware
file has become available.
