   4 Subject: [PATCH 05/13] net: dsa: mt7530: only indicate linkmodes that can be
   5  supported
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit

  10 Now that mt7530 is not using the basex helper, it becomes unnecessary to
  11 indicate support for both 1000baseX and 2500baseX when one of the 803.3z
  12 PHY interface modes is being selected. Ensure that the driver indicates
  13 only those linkmodes that can actually be supported by the PHY interface
  14 mode.
