[dpdk-dev] [PATCH v3 0/8] support PDCP-SDAP for dpaa2_sec

The SDAP is a protocol in the LTE stack on top of PDCP. It is
dedicated to QoS.

The difficulty of implementing this protocol is because the
PDCP change behavior regarding encryption and authentication
of the SDU it receives. In effect PDCP shall not encrypt the
SDAP SDU but must authenticate it (when encryption and
authentication is enabled).

A new field is added in the PDCP xform to specify SDAP is enabled.
The overall size of the xform is not changed, as hfn_ovrd is just
a flag and does not need uint32. Hence, it is converted to uint8_t
and a 16 bit reserved field is added for future.

The corresponding test cases and test vectors are added in the test
application.

This patch need Techboard approval as there is a change in API
without a deprecation notice from last release.
This patch is required to support the upcoming development of
5GNR protocol - SDAP in near future. If the patch is not approved
in the current release, we may not be able to support SDAP for next
1 year which is not accceptable for the customers.

changed in v3:
- fixed signoff
- fixed typo in 1/8

Changes in v2:
- removed unnecessary API documentation from security guide.
- fix clang build
- updated release notes
