  27           Selecting this option, rx has priority over Tx (only for Giga
  28           Ethernet device).
  29           By default, the DMA arbitration scheme is based on Round-robin

  71           (RING) and linked-list(CHAINED) mode. In RING mode each descriptor
  72           points to two data buffer pointers whereas in CHAINED mode they
