  /* The fields in this structure are arranged so that they can be
   * picked up two at a time with 128-bit loads.
   *
   * Because of flipped bit order for this CRC polynomials
   * the constant for X**N is left-shifted by 1.  This is because
   * a 64 x 64 polynomial multiply produces a 127-bit result
   * but the highest term is always aligned to bit 0 in the container.
   * Pre-shifting by one fixes this, at the cost of potentially making
   * the 32-bit constant no longer fit in a 32-bit container (thus the
   * use of uint64_t, though this is also the size used by the carry-
   * less multiply instruction.
   *
   * In addition, the flipped bit order and highest-term-at-least-bit
   * multiply changes the constants used.  The 96-bit result will be
   * aligned to the high-term end of the target 128-bit container,
   * not the low-term end; that is, instead of a 512-bit or 576-bit fold,
   * instead it is a 480 (=512-32) or 544 (=512+64-32) bit fold.
   *
   * This cause additional problems in the 128-to-64-bit reduction; see the
   * code for details.  By storing a mask in the otherwise unused half of
   * a 128-bit constant, bits can be cleared before multiplication without
   * storing and reloading.  Note that staying on a 128-bit datapath means
   * that some data is uselessly stored and some unused data is intersected
   * with an irrelevant constant.
