937 and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
938 solely on encryption (although decryption is supported as well, but
939 with a more dramatic performance hit)
941 Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
942 8 for decryption), this implementation only uses just two S-boxes of
943 256 bytes each, and attempts to eliminate data dependent latencies by
