Hi Lijuan,

The DTS started without error but the nic single core test failed on a
"connection timeout - no response from TRex server" when I tried to run it
on an intel nic.
This happens when DTS uses arm-dell (traffic generator) to send packets
to arm-gigabyte (DUT) using the Intel nic {Ethernet Controller XL710 for
40GbE QSFP+}
I wonder if you have any clue on this issue?
