MEMBERS
       length
           [DEVICE] number of datums in buffer

       bytes_per_datum
           [DEVICE] size of individual datum including timestamp

       scan_el_attrs
           [DRIVER] control of scan elements if that scan mode control method is used

       scan_mask
           [INTERN] bitmask used in masking scan mode elements

       scan_timestamp
           [INTERN] does the scan mode include a timestamp

       access
           [DRIVER] buffer access functions associated with the implementation.

       scan_el_dev_attr_list
           [INTERN] list of scan element related attributes.

       buffer_group
           [INTERN] attributes of the buffer group

       scan_el_group
           [DRIVER] attribute group for those attributes not created from the iio_chan_info
           array.

       pollq
           [INTERN] wait queue to allow for polling on the buffer.

       stufftoread
           [INTERN] flag to indicate new data.

       attrs
           [INTERN] standard attributes of the buffer

       demux_list
           [INTERN] list of operations required to demux the scan.

       demux_bounce
           [INTERN] buffer for doing gather from incoming scan.

       buffer_list
           [INTERN] entry in the devices list of current buffers.

       ref
           [INTERN] reference count of the buffer.

       watermark
           [INTERN] number of datums to wait for poll/read.
