      net/mlx5: Refactor fragmented buffer struct fields and init flow · 4972e6fa
      Tariq Toukan authored
      Take struct mlx5_frag_buf out of mlx5_frag_buf_ctrl, as it is not
      needed to manage and control the datapath of the fragmented buffers API.
      
      struct mlx5_frag_buf contains control info to manage the allocation
      and de-allocation of the fragmented buffer.
      Its fields are not relevant for datapath, so here I take them out of the
      struct mlx5_frag_buf_ctrl, except for the fragments array itself.
      
      In addition, modified mlx5_fill_fbc to initialise the frags pointers
      as well. This implies that the buffer must be allocated before the
      function is called.
      
      A set of type-specific *_get_byte_size() functions are replaced by
      a generic one.

      IB/mlx5: Unmap DMA addr from HCA before IOMMU · dd9a4034
      Valentine Fatiev authored
      The function that puts back the MR in cache also removes the DMA address
      from the HCA. Therefore we need to call this function before we remove
      the DMA mapping from MMU. Otherwise the HCA may access a memory that
      is no longer DMA mapped.
