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.
