The Traffic I assign to queue's does not get limited according to the 
specific limit, it only get's limited by the global bandwidth limited assign 
to the specific NIC.
e.g. I assign traffic to a queue(argon_d) which is limited to 128Kb... but 
it performs at 256Kb which is what the NIC is set to. therefore not being 
assigned to it's designated queue. is it at all possible that this is a 
problem perhaps with my Network cards... if not... any suggestions?


altq on $uplink_if bandwidth 256Kb hfsc queue { dflt_u, argon_u }
queue argon_u hfsc(realtime 64Kb upperlimit 64Kb)
queue dflt_u hfsc(default upperlimit 128Kb)

altq on $hosting_if bandwidth 256Kb hfsc queue { dflt_d, argon_d }
queue argon_d hfsc(realtime 64Kb upperlimit 64Kb)
queue dflt_d hfsc(default upperlimit 128Kb)

#assign argon traffic
pass out on $uplink_if from to any keep state queue argon_u
pass out on $hosting_if from any to keep state queue argon_d

Kind Regards,
