OK, more info. I just created an OpenBSD 3.9 snapshot image for my
Soekris 4801 so I could do an apples to apples comparison. Same pf
config (queue name changed accidentally, but that's a nop), same
hardware - hfsc works like a champ.
queue root_sis1 bandwidth 100Mb priority 0 hfsc( upperlimit 768Kb ) {qWANRo=
ot}
[ pkts: 0 bytes: 0 dropped pkts: 0 bytes: 0=
]
[ qlength: 0/ 50 ]
[ measured: 0.0 packets/s, 0 b/s ]
queue qWANRoot bandwidth 100Mb priority 7 hfsc( default realtime
128Kb upperlimit 128Kb )
[ pkts: 1100 bytes: 230995 dropped pkts: 0 bytes: 0=
]
[ qlength: 0/ 50 ]
[ measured: 39.8 packets/s, 67.13Kb/s ]
queue root_sis0 bandwidth 100Mb priority 0 hfsc( upperlimit 6Mb ) {qLANRoot=
}
[ pkts: 0 bytes: 0 dropped pkts: 0 bytes: 0=
]
[ qlength: 0/ 50 ]
[ measured: 0.0 packets/s, 0 b/s ]
queue qLANRoot bandwidth 100Mb priority 7 hfsc( default realtime
128Kb upperlimit 128Kb )
[ pkts: 1285 bytes: 246653 dropped pkts: 0 bytes: 0=

[ qlength: 0/ 50 ]
[ measured: 45.6 packets/s, 72.27Kb/s ]
Notice two differences here. 100Mbit instead of 10Mbit - this looks
like driver? and no backlogged queue - yay! I'm going to start poking
more at the driver and see if I can come up with anything, I still
find it strange that fxp works (I'm going to poke at that too and see
if anything pops out at me).
