/* 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.
