Do I get it wrong or do the 32-bit counters also go up and down? Given 
that bsnmpd just retrieves the values from the kernel and sends them over 
SNMP without looking at the values (for the 32-bit counters) this looks 
rather like a problem in the kernel/driver. Do these drivers perhaps use 
multiple threads for receiving?
