Nate, good day.

I see no difference between the -CURRENT from today and from 30th
March (I see that your commit was made at 26th of March, but I am
not sure that mu current was updated after it for the -CURRENT
compiled at 30th of March).
The bad news are that the ALTQ behaves wrong: when the CPU frequency
is changed the bandwidth changes too. Either I am doing something
wrong, or your commit should be polished a bit.
My environment is: Asus A2D running AMD Mobile XP, iwi (Intel
2915ABG) and 7-CURRENT. The pf rules were:
-----
altq on iwi0 bandwidth 3Kb cbq queue { dflt }
queue dflt bandwidth 100% cbq(default)
pass out quick log on iwi0 proto tcp from $my_ip to any flags S/AUSPF \
keep state queue dflt
-----
The interface is running at 22 Mbit/sec most of the time. No polling
was enabled. The bandwidth was measured by the ifstat, powerd was
disabled and I had changed the frequency via sysctl. Four frequencies
were used: 400, 800, 1600 and 2200. The kernel config included the
following ALTQ options:
-----
options ALTQ
options ALTQ_CBQ
options ALTQ_RED
options ALTQ_RIO
options ALTQ_HFSC
options ALTQ_CDNR
options ALTQ_PRIQ
-----
Basically, I made two tests: WAN and LAN downloading over FTP and
HTTP. WAN test was done for the old and new -CURRENTs and LAN test
was done just for the new -CURRENT. All tests were done in the
following manner: ifstat was spawned with the delay of 3 seconds,
files were downloaded by fetch and I manually changed the CPU
frequency via sysctl.
First two logs, ifstat.bw3Kb.old.wan.log and ifstat.bw3Kb.new.wan.log
do show the WAN results. The 100 Kbps corresponds to 400 MHz, 200
Kbps -- to 800 MHz, 410 Kbps -- to 1600 MHz and 560 Kbps -- to 2200
MHz CPU speed. I thought that I was bounded by the WAN link here.
ifstat.bw3Kb.new.local-net.log shows the behaviour for the LAN link
(machines are sitting on the same switch, so only L2 devices are
on the network path): just the same figures and bandwidth is still
changing with the CPU.
ifstat.fullbw.new.local-net.log shows the behaviour for the 100%
bandwidth, but with the ALTQ rules enabled (the '3K' were just
changed to '100%' in the pf.conf). The speed is pretty stable flying
around 20 Mbit/sec.
And ifstat.new.local-net.altq-disabled.log shows the behaviour of
interface bandwidth for pf.conf without any ALTQ rules. The same
as above: 20 Mbit/sec, the interface bound.
