    lib: crc32: add test cases for crc32{, c}_combine routines · efba721f
    Daniel Borkmann authored
    We already have 100 test cases for crcs itself, so split the test
    buffer with a-prio known checksums, and test crc of two blocks
    against crc of the whole block for the same results.
    
    Output/result with CONFIG_CRC32_SELFTEST=y:
    
      [    2.687095] crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64
      [    2.687097] crc32: self tests passed, processed 225944 bytes in 278177 nsec
      [    2.687383] crc32c: CRC_LE_BITS = 64
      [    2.687385] crc32c: self tests passed, processed 225944 bytes in 141708 nsec
      [    7.336771] crc32_combine: 113072 self tests passed
      [   12.050479] crc32c_combine: 113072 self tests passed
      [   17.633089] alg: No test for crc32 (crc32-pclmul)
