From: Pablo de Lara Date: Tue, 3 Jul 2018 08:22:34 +0000 (+0100) Subject: crypto/aesni_mb: support IPsec Multi-buffer lib v0.50 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=58d3852ef57630578f5f2744beb53848fd974e47;p=dpdk.git crypto/aesni_mb: support IPsec Multi-buffer lib v0.50 Adds support for the v0.50 of the IPsec Multi-buffer lib. The library now exposes its version, with the idea of maintaining backwards compatibility in the future, avoiding breaking the compilation of the PMD every time there is a new version available.
