AES-NI GCM Crypto Poll Mode Driver
==================================
* RTE_CRYPTO_AEAD_AES_GCM
-
Limitations
-----------
-* Chained mbufs are supported but only out-of-place (destination mbuf must be contiguous).
+* In out-of-place operations, chained destination mbufs are not supported.
+* Chained mbufs are only supported by RTE_CRYPTO_AEAD_AES_GCM algorithm,
+ not RTE_CRYPTO_AUTH_AES_GMAC.
* Cipher only is not supported.
To build DPDK with the AESNI_GCM_PMD the user is required to download the multi-buffer
library from `here <https://github.com/01org/intel-ipsec-mb>`_
and compile it on their user system before building DPDK.
-The latest version of the library supported by this PMD is v0.48, which
-can be downloaded in `<https://github.com/01org/intel-ipsec-mb/archive/v0.48.zip>`_.
+The latest version of the library supported by this PMD is v0.53, which
+can be downloaded in `<https://github.com/01org/intel-ipsec-mb/archive/v0.53.zip>`_.
.. code-block:: console
- make
+ make
+ make install
As a reference, the following table shows a mapping between the past DPDK versions
and the external crypto libraries supported by them:
============= ================================
16.04 - 16.11 Multi-buffer library 0.43 - 0.44
17.02 - 17.05 ISA-L Crypto v2.18
- 17.08+ Multi-buffer library 0.46+
+ 17.08 - 18.02 Multi-buffer library 0.46 - 0.48
+ 18.05 - 19.02 Multi-buffer library 0.49 - 0.52
+ 19.05+ Multi-buffer library 0.52 - 0.53
============= ================================
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.
