RE: [PATCH v2 0/5] add TLS record processing security offload

> Subject: [PATCH v2 0/5] add TLS record processing security offload
> 
> Add Transport Layer Security (TLS) and Datagram Transport Layer Security
> (DTLS). The protocols provide communications privacy for L4 protocols
> such as TCP & UDP.
> 
> TLS (and DTLS) protocol is composed of two layers,
> 1. TLS Record Protocol
> 2. TLS Handshake Protocol
> 
> While TLS Handshake Protocol helps in establishing security parameters
> by which client and server can communicate, TLS Record Protocol provides
> the connection security. TLS Record Protocol leverages symmetric
> cryptographic operations such as data encryption and authentication for
> providing security to the communications.
> 
> Cryptodevs that are capable of offloading TLS Record Protocol may
> perform other operations like IV generation, header insertion, atomic
> sequence number updates and anti-replay window check in addition to
> cryptographic transformations.
> 
> In record write operations, message content type is a per packet field
> which is used in constructing the TLS header. One session is expected
> to handle all types of content types and so, 'rte_crypto_op.aux_flags'
> is used for passing the same.
> 
> Support for TLS record protocol is added for TLS 1.2, TLS 1.3 and
> DTLS 1.2.
> 
> Changes in v2:
> - Replaced CCS with CHANGE_CIPHER_SPEC (Harry)
> - Split patches to clarify lifetime tracking and notification of the
>   same in rte_crypto_op (Harry)
> - Use 8 bits reserved space in rte_crypto_op to pass content type from
>   application to PMD (in case of record write) and from PMD to
>   application (in case of of record read). TLS 1.3 has content type as
>   part of trailer which would be encrypted and would be removed by PMD.
> - Updated documentation (Harry)
