[Anoob] Supporting library mode is also in the pipeline. But initial target would be support with non-librte_ipsec mode.

[Anoob] Inline protocol support would be added to OCTEON TX2 eth PMD in the next cycle. This is an RFC to introduce the idea of using events in ipsec-segcw, which is required for OCTEON TX2 platform to perform inline ipsec processing.
