DPDK version Crypto library version
============= ================================
16.11 - 19.11 LibSSO KASUMI
- 20.02+ Multi-buffer library 0.53 - 1.0*
+ 20.02 - 21.08 Multi-buffer library 0.53 - 1.0*
+ 21.11+ Multi-buffer library 1.0*
============= ================================
\* Multi-buffer library 1.0 or newer only works for Meson but not Make build system.
however their usage and EAL options remain unchanged.
* AESNI_MB PMD.
* AESNI_GCM PMD.
+ * KASUMI PMD.
