  20           This selects the platform specific bus support for
  21           the stmmac device driver. This is the driver used
  22           on many embedded STM platforms based on ARM and SuperH
  23           processors.

  54           By default, the DMA arbitration scheme is based on Round-robin
  55           (rx:tx priority is 1:1).
