ipfw(8) and additional scheduling algorithm specifications

[David Wolfskill]

I've started looking into configuring ipfw & dummynet to see if
FQ-CoDel might improve things for my home Internet connection
(residential ADSL).

In the process of reviewing the available documentation, I note that
ipfw(8) has:

| ...
|      The following case-insensitive parameters can be configured for a
|      scheduler:
| 
|      type {fifo | wf2q+ | rr | qfq}
|              specifies the scheduling algorithm to use.
| ....

On the other hand, `cd /usr/src/sys/netpfil/ipfw; ls dn_{aqm,sched}*.c`
shows:

dn_aqm_codel.c          dn_sched_fq_codel.c     dn_sched_qfq.c
dn_aqm_pie.c            dn_sched_fq_pie.c       dn_sched_rr.c
dn_sched_fifo.c         dn_sched_prio.c         dn_sched_wf2q.c


(This reflects head @r326875 and stable/11 @r326848.)

So it seems that the list of scheduling algorithms in ipfw(8) is a bit
more restricted than the code supports.

Is this observation correct?  If so, is it intentional?

Thanks!

I've set Reply-To.

Peace,
