Inline processing is limited to a specified subset of traffic. It is often unable to handle more complicated situations, such as fragmented traffic. When using inline processing such traffic is dropped.
Introduce multiple sessions per SA allowing to configure a fallback lookaside session for packets that normally would be dropped. A fallback session type in the SA configuration by adding 'fallback' with 'lookaside-none' or 'lookaside-protocol' parameter to determine type of session. Fallback session feature is available only when using librte_ipsec.
