   4 kernel: phy: add Aquantia PHY AQR111 & AQR111B0
   5
   6 Add the IDs for Aquantia PHY AQR111 and AQR111B0 as found in the GPL sources
   7 of the Netgear RAX120v2 firmware v1.2.8.40.
   8
   9 This is a 5GbE chip but it reports support for 10G. Implement config_init()
  10 to set max speed to 5G.
