Problem:
|
||||||
|
- So basically riffa_sume doesn't do the right thing[tm]
|
||||||

Message from myself:

It seems I was really mistaken for the last weeks
|
||||||
|
If I am not totally mistaken, the following is happening with the netpfga:
|
||||||
|
I was testing sending and receiving packets on the same computer; so I sent a packet on nfX and expected an answer on nf0, which is how I wanted to verify that the card works
|
||||||
|
So I ran tcpdump on nf0, send a packet with ping6 and scapy on nf{0,1,2,3} (edited)
|
||||||
|
I have never seen the switch emitting ANY packet back with tcpdump
|
||||||
|
Now with the card connected to another host, sending neighbor solicitation, I see duplicated packets on the other host - so it seems that it might have worked all the time, just that tcpdump on nfX on the host which contains the card does not show the packets

The testscript now generates 2 packets:
