This is now possible since comphy +support was added to this driver. + +This commit adds the 2500BaseT mode to the list of supported modes when +using 2500BaseX, and was tested on a setup with an Armada385 and a +88E2010 PHY, both with and without the comphy node in the DT. + +Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> +Signed-off-by: David S.
