DPDK Cryptodev is an asynchronous crypto API that supports both Hardware and Software implementations (for more details refer to [DPDK Cryptography Device Library documentation](http://dpdk.org/doc/guides/prog_guide/cryptodev_lib.html)).
-When DPDK support is enabled and there are enough Cryptodev resources for all workers, the node graph is reconfigured by adding and changing default next nodes.

### How to enable VPP IPSec with DPDK Cryptodev support
-DPDK Cryptodev is supported in DPDK enabled VPP and by default only HW Cryptodev is supported.
-To enable SW Cryptodev support (AESNI-MB-PMD and GCM-PMD), we need the following env option:
+When building DPDK with VPP, Cryptodev support is always enabled.
- vpp_uses_dpdk_cryptodev_sw=yes
-
-A couple of ways to achive this:
-* uncomment/add it in the platforms config (ie. build-data/platforms/vpp.mk)
-* set the option when building vpp (ie. make vpp_uses_dpdk_cryptodev_sw=yes build-release)
-
-When enabling SW Cryptodev support, it means that you need to pre-build the required crypto libraries needed by those SW Cryptodev PMDs. This requires nasm, see nasm section below.
+Additionally, on x86_64 platforms, DPDK is built with SW crypto support.
