dst address of a UDP packet is changed, which changes port/addr hash
too, but old route entry was not allocated on the current CPU.  Since
the box only contains 2 CPUs, after the l{port,addr}/f{port,addr}
hash, the problem probably will not show itself ;).  Please run
following test program several times and then unload the NIC module to
see whether you could reproduce the problem (if you have TCP
connections too, you will have to wait 2MSL):

Also, please test following patch:
