This patch updates siw_create_qp() to check for the CONFIG_X86 + cpu_has_xmm4_2
dependent use of the CRC32C instruction offload using libcrypto crc32c-intel.ko.
This patch will by default use crc32c-intel when available, and fall back to the
legacy slicing by 1x libcrypto crc32c.ko code when the instruction offload is
not
availabe.
I don't think every caller should handle checks like this. The crypto
layer should load the right driver
instead and provide the best driver under a generic algorithm name.
Need CPUID module auto probing. I have an older patch that needs some fixes.
