 That would mean that we always handle the softint consuming the packet
 just queued on cpu 0.
 
 The whole idea is to load balance and give others a chance to deal with
 the queued packets.
 
 The question is: what exactly goes wrong when we dispatch the softint on
 another cpu?
 
 Could you try hardcoding cpuid = 1 and see if that works?
