   4 Subject: [PATCH] net: mvneta: drop use of phylink_helper_basex_speed()
   5
   6 Now that we have a better method to select SFP interface modes, we
   7 no longer need to use phylink_helper_basex_speed() in a driver's
   8 validation function, and we can also get rid of our hack to indicate
   9 both 1000base-X and 2500base-X if the comphy is present to make that
  10 work. Remove this hack and use of phylink_helper_basex_speed().
