I'm glad I saw this come through, I've spent a fair amount of time trying to figure out what was wrong. CBQ in RELENG_6 is still doing what this PR suggests using the pfSense shaper setup (we've disabled it for now). HFSC appears to work for a while (at least I see no bad latencies immediately after load), but it eventually (in some cases immediately) also tends to cause massive latencies (completely idle connection showing 700ms pings w/ altq and 30ms pings w/out). It can be challenging to duplicate this with setups going from working to broken to working. --Bill
