New functionality:
- Preserves existing scalar implementation.
- Adds AVX2 optimized Fletcher-4 computation.
- Fastest routines selected on module load (benchmark).
- Test case for Fletcher-4 added to ztest.
New zcommon module parameters:
- zfs_fletcher_4_impl (str): selects the implementation to use.
"fastest" - use the fastest version available
"cycle" - cycle trough all available impl for ztest
"scalar" - use the original version
"avx2" - new AVX2 implementation if available
Performance comparison (Intel i7 CPU, 1MB data buffers):
- Scalar: 4216 MB/s
- AVX2: 14499 MB/s
See contents of `/sys/module/zcommon/parameters/zfs_fletcher_4_impl`
to get list of supported values. If an implementation is not supported
on the system, it will not be shown. Currently selected option is
enclosed in `[]`.
