	  api calls use to perform spi transactions. this queue needs to be as deep
	  as the longest set of spi_buf_sets used, where normal spi operations are
	  used (equal length buffers). it may need to be slightly deeper where the
	  spi buffer sets for transmit/receive are not always matched equally in
	  length as these are transformed into normal transceives.
