From 7c04c8489115a46cc2ad6769f2e0c96237b6e75c Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Mon, 11 Apr 2022 10:46:17 +0100 Subject: [PATCH] net: dsa: mt7530: only indicate linkmodes that can be supported MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that mt7530 is not using the basex helper, it becomes unnecessary to indicate support for both 1000baseX and 2500baseX when one of the 803.3z PHY interface modes is being selected. Ensure that the driver indicates only those linkmodes that can actually be supported by the PHY interface mode.
