+Subject: [PATCH 04/13] net: dsa: mt7530: drop use of
+ phylink_helper_basex_speed()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Now that we have a better method to select SFP interface modes, we
+no longer need to use phylink_helper_basex_speed() in a driver's
+validation function.
