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.
