Hi,
for me this new prio queue queueing just doesn't work on pppoe(4).
I tested this now three times switching between the new prio and old
altq/priq back and forth. With altq/priq I can use priorized ssh very
smoothly while saturating my uplink with a 'nc foo.bar </dev/zero'.
With the new prio I get echo delays of several seconds.
Part of my pf.conf:
[...]
altq on pppoe0 priq bandwidth 200Kb queue { voip, lowdelay, default, bulk }
queue voip priority 7 qlimit 3 priq
queue lowdelay priority 6 qlimit 5 priq
queue default priority 3 qlimit 30 priq(default)
queue bulk priority 1 qlimit 50 priq
[...]
pass out proto tcp to port ssh queue(bulk,lowdelay)
[...]
With prio I simply replaced the queue(...) by prio(...) statements and
the same numbers I used for priority in altq/priq:
queue(bulk,lowdelay) -> prio(1,6).
I don't know much about OpenBSDs network stack, but could it be that
some lower level kernel driver (maybe pppoe(4)) has a queue which is
dropping packets? Why else would altq/priq need the bandwidth
parameter?!?
