Hi,

Here is the lscpi output -

81:00.0 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SF=
I/SFP+ Network Connection [8086:10fb] (rev 01)
81:00.1 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SF=
I/SFP+ Network Connection [8086:10fb] (rev 01)
84:00.0 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SF=

I/SFP+ Network Connection [8086:10fb] (rev 01)

I am using Fedora 18, DPDK version 1.5.0r1

The first two ports (as in lspci output) are connected to the switch and Li=
nux is able to ping using these.
When they are in linux control, I see that auto negotiation is done for 10 =
Gbps
I unbind 81:00.0 and apply igb_uio

Now when I start the DPDK application, I get the error which I am attaching=
 with DEBUG set to y.
Somehow DPDK is not able to recognize the NIC.

Any hints if someone has encountered a similar issue.

Regards
-Prashant
