Thank you very much for this hint. Unfortunately my current idea would require 
about 1000 bands:

To emulate a wireless network I have to assign a packet loss depending on the 
target IP address. The idea was to use a PRIO qdisc with n bands for n nodes 
and use filters to assign packets to the appropriate band depending on the 
target address.

Since I am unsure about side-effects of an alteration of TC_PRIO_MAX to a 
signifficantly higher value, an alternative would be helpful.

Thanks in advance.
