AES-NI GCM PMD migrated previously from Multi-buffer Crypto library to ISA-L Crypto library, to support several features that were not supported by that time, such as GMAC algorithm and Scatter-gather list.
Since version 0.45, Multi-buffer library (https://github.com/01org/intel-ipsec-mb) supports all these features, the PMD can link against this library again. This will improve maintainability, as now AESNI GCM PMD will share the same library as AESNI MB PMD, having one less library to link against. It also adds support for 192-bit keys. In terms of performance, there is a marginal difference between those libraries, within a 0.5% difference for several buffer sizes. This patchset is migrating the PMD to link against Multi-buffer library v0.45. The next version will be released in the coming months, which contains some improvements and API changes, so this patchset will be rebased to support it, if it is released before the merge deadline.
