[dpdk-dev] [PATCH 4/9] test/crypto: add sgl test cases for ip and oop

Nowak damianx.nowak at intel.com
Mon Jun 3 16:50:43 CEST 2019


From: Damian Nowak <damianx.nowak at intel.com>

This patch adds test cases for snow3g in-place
and out-of-place auth-cipher operations with
scatter-gather lists as input and output mbufs.
Test cases include digest generation with buffer
encryption and buffer decryption with digest
verification.
