Hi Zhenlei,

No, if you just do a ping, all is OK. But, whenever you start an scp transfer
(while pinging), you start getting duplicate packets for both ping and scp. See
attached files. 

We disable all offloadings during the tests:

ifconfig vmx0 -vlanhwtso -vlanhwfilter -vlanhwtag -vlanhwcsum -txcsum -rxcsum
-tso4 -tso6 -lro -txcsum6 -rxcsum6
