It's also not clear to me what anzp means with bandwidth.  If he means the 
bandwidth parameter, then it's the nic speed.  The bandwidth parameter has to 
be the NIC speed so 10 or 100 mbit.
But you can add a bounded class to the root qdisc so you can limit all 
bandwidth and this can be different from the nic bandwidth.
