"""DPDK cryptodev performance test suite.

The main goal of this test suite is to utilize the dpdk-test-cryptodev application to gather
performance metrics for various cryptographic operations supported by DPDK cryptodev-pmd.
It will then compare the results against predefined baseline given in the test_config file to
ensure performance standards are met.
