+Subject: [PATCH 08/13] net: dsa: mt7530: move autoneg handling to PCS
+ validation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Move the autoneg bit handling to the PCS validation, which allows us to
+get rid of mt753x_phylink_validate() and rely on the default
+phylink_generic_validate() implementation for the MAC side.
