Hi Roberto,

If that is the case, you can use your NetFPGA as a generic four-port
NIC (using "reference nic" NetFPGA bitfile) and run openVswitch with it.

I'm sure about that, but that's the only hw I own at the moment.
This configuration has worked fine with the
usual ofdatapath/ofprotocol daemons connected to a NOX controller.
What I'm trying to do is testing OpenVSwitch 1.1.2 on this hw.
Why so old? The latest "stable" OVS is version 1.2.1.
Well, the 1.1.2 version is most recent release including the
INSTALL.OpenFlow doc. This is the only reason.
I followed the procedures described in INSTALL.Linux and
INSTALL.OpenFlow (and some other step-by-step howto's found around).
What I obtain is that ovs-openflowd successfully connects to the
controller (either NOX or ovs-controller through the localhost
interface) but two hosts connected to two NetFPGA ports cannot ping
each other. From the controller output I don't see any flow coming
from the NetFPGA.
How does OVS talk to the NetFPGA? Did you write a dpif
implementation, or do the NetFPGA ports appear as Linux network
devices, or...?
NetFPGA ports appears as Linux net devices. I used the ovs-dpctl
tool to create a datapath out of the 4 NetFPGA interfaces as
described in the ovs documentation
Unfortunately I have not found any "official" documentation about
putting OpenVSwitch to work with NetFPGA cards. This brings me to
think that NetFPGA cards are not supported by OpenVSwitch.
Open vSwitch has no special support for NetFPGA. (But if you want to
contribute some, I think we'd be open to that.)
Ok, thanks anyway for you kind answer.
