Hi Haris,
You mentioned you are using release/1.0.0 branch for NetFPGA design.
Please see the instruction below and use the correct branch for it.
http://www.openflow.org/wk/index.php/CentOS_NetFPGA_Install
If you have a quad NIC please run the regression test after the
installation to make sure it's been successful.
Also, one user from this forum reported that it still won't work on
the latest CentOS. They switched back to CentOS5.4 to make it work.
I'm going to reproduce it sooner but please see if that's the case for
you.
Thank you,
Tatsuya
I assume you are using NetFPGA branch seeing the instruction, not the
pure
release/1.0.0 branch.

Hi all,
I am using the git version of the reference openflow implementation

out messages.
From a custom controller I send the following message:

Unfortunately thought I wasn't able so far to receive a packet on port
1. The flow table when I send the packet is emtpy. Has anybody else
observed this behaviour and is it maybe a bug in the code or my
message parameters are incorrect?
