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​.
