Description Pablo de Lara 2022-12-14 11:58:00 CET 
As number of threads is increased, performance per core on AESNI MB PMD decreases (it should stay constant). The root cause of this issue is a global variable in the IPSec Multi-buffer library. A patch has been generated to fix it on the library, so users running the PMD with multiple threads are encouraged to get the latest version (1.3.0) with the patch.
