This structure contains data required to create a PDCP security session. Definition at line 536 of file rte_security.h. Field Documentation int8_t bearer PDCP bearer ID Definition at line 537 of file rte_security.h. uint8_t en_ordering Enable in order delivery, this field shall be set only if driver/HW is capable. See RTE_SECURITY_PDCP_ORDERING_CAP. Definition at line 541 of file rte_security.h. uint8_t remove_duplicates Notify driver/HW to detect and remove duplicate packets. This field should be set only when driver/hw is capable. See RTE_SECURITY_PDCP_DUP_DETECT_CAP. Definition at line 546 of file rte_security.h. enum rte_security_pdcp_domain domain PDCP mode of operation: Control or data Definition at line 548 of file rte_security.h. enum rte_security_pdcp_direction pkt_dir PDCP Frame Direction 0:UL 1:DL Definition at line 550 of file rte_security.h. enum rte_security_pdcp_sn_size sn_size Sequence number size, 5/7/12/15/18 Definition at line 552 of file rte_security.h. uint32_t hfn Starting Hyper Frame Number to be used together with the SN from the PDCP frames Definition at line 556 of file rte_security.h. uint32_t hfn_threshold HFN Threshold for key renegotiation Definition at line 558 of file rte_security.h. uint8_t hfn_ovrd HFN can be given as a per packet value also. As we do not have IV in case of PDCP, and HFN is used to generate IV. IV field can be used to get the per packet HFN while enq/deq. If hfn_ovrd field is set, user is expected to set the per packet HFN in place of IV. PMDs will extract the HFN and perform operations accordingly. Definition at line 567 of file rte_security.h. uint8_t sdap_enabled In case of 5G NR, a new protocol (SDAP) header may be set inside PDCP payload which should be authenticated but not encrypted. Hence, driver should be notified if SDAP is enabled or not, so that SDAP header is not encrypted. Definition at line 573 of file rte_security.h. uint16_t reserved Reserved for future Definition at line 575 of file rte_security.h.
