MFC r217911:
  Add support for RTL8105E PCIe Fast Ethernet controller. It seems
  the controller has a kind of embedded controller/memory and vendor
  applies a large set of magic code via undocumented PHY registers in
  device initialization stage. I guess it's a firmware image for the
  embedded controller in RTL8105E since the code is too big compared
  to other DSP fixups. However I have no idea what that magic code
  does and what's purpose of the embedded controller. Fortunately
  driver seems to still work without loading the firmware.

  While I'm here change device description of RTL810xE controller.
