 HFSC can be used as a workaround since it can express everything that
 is possible with CBQ:
 
 altq on $lan_if hfsc bandwidth 100Mb queue { qLocal, qExt }
 queue qLocal bandwidth 90Mb hfsc(default)
 queue qExt bandwidth 10Mb hfsc(upperlimit 10Mb) { qExtFast, qExtSlow }
 queue  qExtFast priority 7 bandwidth 80%
 queue  qExtSlow priority 1 bandwidth 20% hfsc(red)
