Follow the recommendations stated in the Turris Omnia DTS for eth2: "In case SFP module is present, U-Boot has to enable the sfp node above, remove phy-handle property, and add managed = "in-band-status" property." The boot script is written in a way, that it works for all U-Boot versions deployed by the vendor so far (2015.10-rc2, 2019.07). Signed-off-by: Klaus Kudielka <klaus.kudielka@gmail.com>
