   4 Subject: [PATCH] drivers: net: dsa: felix: Allow PHY to AN 10/100/1000 with
   5  2500 serdes link
   6
   7 If the serdes link is set to 2500 using interfce type 2500base-X, lower
   8 link speeds over on the line side should still be supported.
   9 Rate adaptation is done out of band, in our case using AQR PHYs this is
  10 done using flow control.
