Hi,
I'm trying to test the l2fwd sample application by passing packets from
traffic generator.
I'm doing this testing in a VM with a configuration hav?ing virtual NIC
port.
When I bind the virtual NIC port with the igb driver, the interface doesnt
get listed in the "ifconfig" output.
Also the virtual NIC port fails to receive packets from the traffic
generator after the interface is bound to igb driver.
Please let me know whether this is the expected behavior and also let me
know how I can make the traffic pass through the port
bound to the igb driver.
While starting the VM the interfaces currently active:

After this when I send traffic with this MAC >>> 080027b73a25
traffic does not flow to this interface
