What I am aware about:
a) rte_security_ops. get_userdata
[Akhil] I believe Cavium added some patches in ipsec-secgw app for its usage and I believe they do have implementation for that. Also I cannot see any changes in rte_security for its support in PMDs.

b) RTE_SECURITY_ACTION_TYPE_INLINE_PROTOCOL

[Akhil] Cavium supports it.

c) rte_security_capability.ol_flags:
    RTE_SECURITY_PDCP_ORDERING_CAP
    RTE_SECURITY_PDCP_DUP_DETECT_CAP

[Akhil] PDCP is not currently supported by any of the vendors except NXP and NXP do not support these capabilities.
For this also, I don’t see any change in the library. It would be only PMD which needs to support it.

    RTE_SECURITY_TX_HW_TRAILER_OFFLOAD
    RTE_SECURITY_RX_HW_TRAILER_OFFLOAD

[Akhil] Same here, these are all PMD capabilities which do not require any change in rte_security.

After another thought - it is probably unfair to keep whole lib as experimental because few things are missing.
But I think things that are unimplemented (or related to them) need to stay in 'experimental' state.

[Akhil] I do not foresee any changes in library, so I believe experimental is not required. Please correct me if this is incorrect understanding.
