From: Akhil Goyal Date: Mon, 30 Sep 2019 14:40:43 +0000 (+0530) Subject: security: add HFN override option in PDCP X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=badac76cec520f4e29f016b0bb1c3c56bf519f7e;p=dpdk.git security: add HFN override option in PDCP 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 in pdcp_xform is set, application is expected to set the per packet HFN in place of IV. Driver will extract the HFN and perform operations accordingly.
