When I am using aes cmac with intel multi buffer library from DPDK. I am receiving an segmentation fault in aes_cmac_subkey_gen_avx512(). This segmentation fault appears at times. Thread 5 "lcore-slave-1" received signal SIGSEGV, Segmentation fault.

On compiling the above intel multi buffer library and running LibTestApp from multi buffer library. It is showing Illegal Instruction. AES-CFB128 standard test vectors: ........................ ...Pass SHA standard test vectors (N jobs = 1): .................... ...Pass Testing AVX512 interface Illegal instruction (core dumped) I am not able to understand the issue. Request you to help me in this regard. Please revert for any clarification. -- Thanks and Regards Suraj R Gupta
