[dpdk-dev] [PATCH v2 2/2] crypto/aesni_gcm: support IPsec Multi-buffer lib v0.49

["Kovacevic, Marko" <marko.kovacevic@intel.com>]

Adds support for the v0.49 of the IPsec Multi-buffer lib,
which now gets compiled and installed as a shared object.
Therefore, there is no need to pass the AESNI_MULTI_BUFFER_LIB_PATH

Signed-off-by: Marko Kovacevic <marko.kovacevic@intel.com>

 In order to enable this virtual crypto PMD, user must:
 
-* Export the environmental variable AESNI_MULTI_BUFFER_LIB_PATH with the path where
-  the library was extracted.
-
 * Build the multi buffer library (explained in Installation section).
 
 * Set CONFIG_RTE_LIBRTE_PMD_AESNI_GCM=y in config/common_base.
