      netxen: cut-through rx changes · d9e651bc
      Dhananjay Phadke 提交于
      NX3031 supports cut-through operation where ingress packets are
      directly dma'ed into host buffers to reduce latency.
      
      This requires larger dma buffers (2kb) and different alignemnt.
      
      The buffer posting logic is changed a bit. The free rx buffers
      are maintained in linked list, since the received reference
      handles can be out of order. However rx descriptors are still
      posted sequentially, indexed by producer.
