Will add comments here.
/** 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.
*/
But using a different name may not be useful. Here we want to specify that
HFN can be overridden from the per packet value.
Now the usage is explained in the comments. I believe hfn_ovrd is enough to
explain the intent. Though not a very strong opinion on this.
Will send the v2 shortly.
