[dpdk-dev] [PATCH v3 0/3] add fallback session

[Marcin Smoczynski]

Add fallback session feature allowing to process packets that inline
processor is unable to handle (e.g. fragmented traffic). Processing
takes place in a secondary session defined for SA in a configuration
file.

This feature is limited to ingress IPsec traffic only. IPsec
anti-replay window and ESN are supported in conjunction with fallback
session when following conditions are met:
 * primary session is 'inline-crypto-offload,
 * fallback sessions is 'lookaside-none'.

v2 to v3 changes:
 - doc and commit log update - explicitly state feature limitations

v1 to v2 changes:
 - disable fallback offload for outbound SAs
 - add test scripts
