   4 Subject: [PATCH] net: phy: aquantia: add AQR111 and AQR111B0 PHY ID
   5
   6 Add Aquantia AQR111 and AQR111B0 PHY ID. These PHY advertise 10G speed
   7 but actually supports up to 5G speed, hence some manual fixup is needed.
   8
   9 The Aquantia AQR111B0 PHY is just a variant of the AQR111 with smaller
  10 chip size.
