61 * Because of flipped bit order for this CRC polynomials
62 * the constant for X**N is left-shifted by 1. This is because
63 * a 64 x 64 polynomial multiply produces a 127-bit result
64 * but the highest term is always aligned to bit 0 in the container.
65 * Pre-shifting by one fixes this, at the cost of potentially making
66 * the 32-bit constant no longer fit in a 32-bit container (thus the
67 * use of uint64_t, though this is also the size used by the carry-
68 * less multiply instruction.
69 *
70 * In addition, the flipped bit order and highest-term-at-least-bit
71 * multiply changes the constants used. The 96-bit result will be
72 * aligned to the high-term end of the target 128-bit container,
73 * not the low-term end; that is, instead of a 512-bit or 576-bit fold,
74 * instead it is a 480 (=512-32) or 544 (=512+64-32) bit fold.
75 *
76 * This cause additional problems in the 128-to-64-bit reduction; see the
77 * code for details. By storing a mask in the otherwise unused half of
78 * a 128-bit constant, bits can be cleared before multiplication without
79 * storing and reloading. Note that staying on a 128-bit datapath means
80 * that some data is uselessly stored and some unused data is intersected
81 * with an irrelevant constant.
