Subject: [PATCH v3 2/6] crypto: crc64 - add crc64-iso3309 framework
From: Kamlesh Gurudasani <kamlesh@...com>
Hardware specific features may be able to calculate a crc64-iso3309,
so provide a framework for drivers to register their implementation.
If nothing is registered, fallback to the generic table lookup
implementation. The implementation is modeled after the crc64-rocksoft
equivalent.
Add testmgr, tcrypt tests and vectors for 64-bit cyclic
redundancy checks (CRC) according to the ISO 3309 standard.
The ISO 3309 64-bit CRC model parameters are as follows:
Generator Polynomial: x^64 + x^4 + x^3 + x + 1
Polynomial Value: 0x000000000000001B
Initial value: 0x0000000000000000
Reflected Input: False
Reflected Output: False
Xor Final: 0x0000000000000000
