No packets received no the receiver side in the simple pkt-gen example #41

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Run pkt-gen tx and rx on the same 10G NIC with ixgbe driver
2. Sender: sudo ./pkt-gen -i data0 -f tx -l 60
3. Receiver: sudo ./pkt-gen -i data0 -f rx

What is the expected output? What do you see instead?

Expected: receiver receiving all the packets

Actual output: (no packet received by the receiver..)
Sender side:

Seems that it did not work across two machines when the destination mac address 
and ip were set.

I have also configured the sender with netmap, while the receiver simply used 
the original driver, but then tcpdump did not find any packets..

Maybe I missed something.

Thank you in advance.
